Awesome video...lol...that's my car...thanks so much for taking the time out of your trip to drop by. Still waiting for the muffler shop to get me hopefully tomorrow now but I will update this thread with the update after the Cat change..Thanks again and I wish you and then family well..it was such a pleasure to meet you.
Thanks for this video! My 2003 explorer had the same issue and this vodeo diagnosed it perfectly from the loss of power to bad shifting. Like a new truck again!
Great tip Brian. I have gotten so used to using my backpressure gauge set or an infrared thermometer for restricted cat diagnosis. Really appreciate the use of the baro pid, always used graphing O2's over each other for efficiency diag. Thanks for the great vids and congrats on the new shop/house, you deserve it.
Great video great info. Much respect to you being a ford only technician as I find them the most frustrating vehicles to work on at my shop. I have dreamed of strangling many a ford engineer, as I'm sure you have.
Sensational video series! In this video, the loud rattle during road test, pinging or cat rattle? I ask because I have an 07 5.4 with a severe power issue. It was driven by PO way too long with a major manifold leak on bank 1 and (prob from it) a front O2 on that side showing 0V and code locked lean. I've replaced the O2 and all plugs and fuel filter. Idle is good, no noises etc. Light driving decent, under high load, engine groans like it's opening the throttle fully, bogs down and starts to ping and rattle. Backing off, it settles down and idles etc. I'm already suspect of the cat since downstream O2 on that side fluctuates inline with upstream O2 while downstream on other side is pretty stable around .6v.. If that under load rattle in your video is engine knock, it's what mine does, just a terribly expensive part to replace on spec.. Thanks for any time you're willing to throw at this! Greg
when my converters plugged up, i cut them out, hollowed them and reinstalled and use defoulers to get the sensors out so there isn’t an engine light, runs great and sounds mean with the exhaust system on it!
When you cut out the catalytic converters on your truck didn't the truck run great my problem cylinder number 3 misfire and I think the cats are clogged 300K on a 01 F150 5.4 l
I did the same minus the O2 sensor defoulers on my superduty diesel. Runs awesome and still passes emissions just fine as long as I don't use a lead foot.
I ran a dead cylinder on bank one for about a week until I figured out the problem, and ruined my converter on that side. It would rattle occasionally, but it was drivable. Anyhow, started up a mountain the other day & the truck wouldn’t go over 35mph. No power. Every time I accelerated it would rev to maybe 3,000 rpm & the engine would act like I hit the rev limiter & the RPMs would drop to idle. Either the right side converter, or the exhaust past the converter was occluded with what I imagine was the innards of that converter. Got to the top of the mountain & steadily accelerated after there wasn’t an incline to deal with. Finally, the truck made a loud pop & blew a cloud of black dust out the tail pipe. It ran great after that. Lol
@Ford Techmakuloco I have a 2004 ford Taurus that I just picked up cheap.. I'm getting po420 and po430 codes.. my scanner isn't as fancy as yours but I can look at the live data and it shows the voltage pouncing between .11 to .6 volts on the downstream O2 sensors.. I'm suspecting it's bad cats because when I bought the car, I had to replace a leaky heater core hose assembly.. there for I'm willing to bet that the car has been run hot a time or to.. I've had the car for a couple of weeks and I'm not losing any coolant and I don't see any traces or water in the oil.. so I don't really think that I have a bad intake gasket.. when I first started working on the car I did have a vacuum leak do to a O ring. I fixed that and the po173 and 174 never came back.. after that.. I went and got some plug non-foulers and spaced out the o2 sensors.. I thought that would cure it and I was able to drive the car quit and ways before it tripped the light.. so what say you? Do these sound like the symptoms of burned out cats?
maybe the owner fixed the p0305 but he didnt fix it in time and it screwed the cat converter up, a quick and dirty test for a suspect plugged exhaust is get the o2 sensor readings up like you did and floor the thing see if they go full rich if they do definetly suspect the cat or cats.
Check this out .. If it has burnt out the cat , And by the sound of it being broken up inside the metal housing it has . Then how would it become stopped up per say and restrict the flow output ? Unless it has pushed the cat material out and into the muffler? I understand that is what its doing. With the misfire at the cylinder . Is it possible that it could be the pc overloading the air fuel mixture trying to compensate for the reading that the 02 sensors are relaying and causing the misfire to happen under load ?
I have a Ford Transit 350HD with a 3.7L engine and, what I suspect, a rattling catalytic converter on the driver's side. I don’t have a "check engine" light on nor any cat codes when I use my INNOVA 6100P OBD2 tester. I took a rubber mallet, crawled underneath the van, when cold, and tapped on the cat shield and crossover pipe as it connects to the suspected cat. It does make a sound, as if, it had gravel in it. It has less than 26,000 miles on it. The cat shield doesn't look loose. It just, puzzles me, how can the material be loose inside the cat with such low miles and no "check engine" light nor codes.
U know this is an old post, but, hopefully u can give me an answer...my cats have been hollowed out, the can us there but no guts. How can I stop the code or check engine light from coming up? Is there a way??? Tks!
I got a check engine light on my 2007 Ford f150. And was diagnosed with a P0420 code. There probably is an issue with the catalytic converter, but my car runs great. When I accelerate my truck takes right off. Could it most likely be a sensor? Thaks for your awesome vide
have you seen low boost codes with a P0420 on a 2015 f150 2.7l ecoboost. we suspect cat is plugged. no leaks and has new turbos. only passenger side turbo is having problems
I would have thought someone would have asked this already but what caused the cat to overheat and burn out? How many miles on it? Thanks for the Baro tip I did not know that!!
hopefully your still running your channel this ones old. so my uncle thinks his 2013 ford f-150 v6 turbo has a clogged cat he said it feels like he has a misfire but it still has power but i think it still has power because its a turbo. the only thing that gets me is said he smells rotten eggs
Hello. I have a procharged 22 Mustang GT 10r80 and I get a p0430 code but the car runs great it’s averaging 20.4mpg think my issue is it’s flowing to much and not clogged?? I also run a vp fuel mix of 101&91 all the time. Thank you for your help. I have headers on the way but there 7 weeks out still from kooks
I have an 03 f150 4. 6 had it about 10 years and the battery light came on today while I was driving but it still starts and runs fine is it the alternator. the battery is only about a year old. I'm going to try to have it checked tomorrow if that's not it where should I start thanks
I have an 06 expedition with 197k that I've done a bunch to but it's never had any timing work done, it has the dreaded start up rattle, shakes at idle, no ses light So I'm getting ready to get all the parts together if you are coming through oregon at all, we run a full service shop, air, lifts, etc just saying lol
I'm getting an "intermittent" P0430 2014 Ford Flex NA. *Injectors ohm out at 14.5 New plugs, coils and cleaned Throttle body. *Baro is rock steady 103 *Downstream o2's both sit at . 83 volts. STFTR1 Is almost a solid line. STFTR2 has a little wiggle to it. Today I did a KOER Test and it came back with a P1101 MAF code, so I put in a fresh air filter, and tommorow with CRC the MAF Sensor. The acceleration seemed held back up to 6k but after that it gets with the program. Any insight to this data is much appreciated.
I've replaced timing chains, guides, tensioners, plugs, coil packs, injectors, fuel filter, crankshaft sensors, and Vct solenoids. Truck runs better with the vct's unplugged but still runs like crap. I don't get it. Are my cats plugged. I have rough idle, no power and can't tow anything
I had this problem on my E250 2007. Another thing to mention is your car won't go fast than 45 mph. I spent over 2000$ at the garage. Ya I changed all the coils, and plugs. Quick tip if you don't have the scan tool is to pull the Oxygen sensor before the cat if there is a lot of air pressure then your cat is blocked. I could have saved over 1200$ here on this ones boys and girls. Some mechanics don't know crap. and are just glorified parts swappers.
did you cut the catalytic converters off of your Ford I own a 2001 Ford F150 5.4 L I believe the cats are clogged no exhaust really coming out the tailpipe and cylinder number 3 misfire along with shaking I replaced all parts I could in cylinder and comes up with code pending shortly after cylinder 3 misfire shaking at 45 miles an hour where you able to save your cat's or replace either way I was going to do straight pipe and save O2 sensors because they are on the pipe not the cat just seeing if replacing your cat's help
Quick Questions - Background Info - 2009 F150 4.6L 3V, Automatic Transmission, 58K miles, I drive in tropical weather all year long (outside temp is never over 90eg or under 60deg) ... I basically use regular unleaded gas all year long except for three times a year When I run a tankful of 92 octane. I have tried several fuel system cleaning products and methods to keep my engine fuel tank and fuel delivery system in top notch shape. None of which left me feeling that anything made a noticeable difference except for the BG 44K that you recommended. After using BG 44K I immediately noticed that my MPG numbers fell drastically. From 17MPG to 12MPG and it now averages about 13MPG. I suspect that the 13MPG is the true number because I backed that up twice with actual gas tank fill up gallon/miles numbers. Really close to 13MPG. My first question - How can i get those MPG up? I don't ricky road rage race my truck but have had it up to 100MPH once or twice since buying it new. I'm just an old truck guy that takes exceptional care of my vehicles and don't ever abuse them. I've already done the FOMOCO sparkplug and coil change, trans filter/gasket and oil change with FOMOCO parts (and I replaced the trans bulkhead adapter while pan was down), replaced high quality air filter, Clean fresh engine oil is changed every 4000miles on average (I've only used Mobile 1 or Royal Purple oil from day one). I check my truck monthly for any trouble codes and have no codes listed or stored. My upcoming next planned maintenance is lubing the drive shaft splines with FOMOCO PTFE grease. I don't have any oil/fluid leaks. Compression is normal across all cylinders. All coil packs are good to go and within normal readings. Pulse width is normal. Acceleration is immediate and smooth. Cruising speeds and ride is normal. Second question - Will adding second can of BG 44K help increase MPG or even make a difference? Third Question - Am I missing some mechanical process or step to help get the MPG back up? Appreciate any advice and or recommendations. Probably is what it is but would like to squeeze a little more MPG without losing power availability and drivability. Thanks ahead of time. Rick
It’s been six years lol You mind sharing any feedback and or thoughts for the next weary 09 owner experiencing similar issues? The code I struggle with is small evap leak P0442. One shop thought it was canister purge but comes and goes. Another shop said it shouldn’t effect anything noticeable. The fuel inlet is cleaned regularly using the funnel. I did the fuse relocation kit for fuel pump as I noticed min was showing signs of excessive heat. For some reason when my truck gets to below half a tank it seams more responsive with noticeable acceleration (similar to when you install a new battery and are performing relearn process). Also my ambient air temp reading on the dash is very inconsistent. I’ve seen my barrow numbers and open/closed loop jump around watching live data but i’m still trying to educate myself on reading fuel trims.
What's your take on Cataclean? Do you think it helps to remove some build up if your cat isn't in a failing state? I haven't gotten a code, but my car just sounds a little different. Thank you for all of your videos and tips.
I have a 2005 f150 5.4l and live in california. What happens if i add a non complaint california catalytic converter to my truck? Will it still pass smog?
Ford tech. I'm currently getting an intermittent p0420 212k on my 05 no other codes, and does not have anywhere near that low of power. My engine has been more lively. I don't have any other codes. By any chance the cats are just old and in need of a change or something is causing them to fail? I would hate to just throw new cats just to have them come back 6 months to a year later. Your input would be greatly appreciated.
P0420 code is a air fuel ratio code. My stock 3v 5.4 has 260k miles has gotten that code for bad spark plugs(computer leaned the tune) also plugged fuel filter(computer leaned the tune) code went away after tune up.
I just recently fixed my right hand side exhaust manifold and now I'm getting a p0420 code on the right hand bank. Do you think that the exhaust leak on that side over the course of 3 years would have had anything to do with it?
I have 3 cats & removed one for sounds affects, I also have a cherrybomb m80 as resonater & the rest straight piped, do you think that me removing 1 cat is causing a p0420 code on my car, I has all this done a year ago & this is just now happening
Brian... do you have a source on where to get a 2008 F-150 XLT Catalytic Converter Bank 2 Driver's side?. My Brother-in-Law has his own shop, and he was just quoted $1,055. Wow... Any sources would be much appreciated. Thanks...
My 98' 5.4 2V Expedition keeps blowing of the larger DPFE hose and there's a lot of hot exhaust coming from it . and also yes , if I floor it from a stop it will just stay in first even though it shifts fine through all gears under normal acceleration .
Thanks for your reply your videos are really helpful . I did the mallet thing and also loosened the flange at the manifold and drove it around , It ran worse at low speeds but above 50 it found its legs ! I guess because it forced the pipes apart enough to relieve the back-pressure . I know I cant drive around like that( it sounds like an airplane) but at least I know what the problem is . Thanks again !
Thanks . I'm pretty sure what burned /clogged it up too . I had a leaking head gasket and a cracked radiator and overheated a couple times . Baked antifreeze in there , plus it's all broken up . I ordered a complete California direct fit assembly . I have since replaced the radiator and successfully sealed the head gasket with Prestone's new three part kevlar head gasket repair .
I had the loss of power issue, the occasionals rattle on start up, and the P0420 code to boot. When I pulled the cats off they were perfectly clear of any obstruction. Can the cats material be bad, thus throw a code and therefore electronically restrict power even though theyre not obstructed?
Im on western ky ..i have a 2012 explorer xlt..i think im having cat issues..cylynder 6 and 3 misfiring. Loss of power shuttering hard shifts idles rough and low. Is this signs of a bad cat converter?
I have a f150 2015 and my sync up drive shows p0420 and the truck have the same noise, I went to the dealer and they refuse to replace the part as a warranty cause the check engine light isn't on. What can I do
My cats have 230k i get a misfire under load on cylinder 3 and a low threshold on bank 2 ive already replaced alot of parts should i bite the bullet and buy new cats
RUclips gave me an ad for CataClean at the beginning of this video first time I watched it - LMAO!!! Nice try - NOT happening! HMU if you do another one of these road trips, Brian, especially if you come to FL!
I think this could be my problem on my 04 f150 5.4, but there's no rattle or sound like that when driving, just a huge loss of power second gear. I'm am getting lean bank 1 and previously , cylinder 5 and 6 misfire codes.
did you replace the catalytic converters or cut them off on your V for I have a 5 for 2001 F150 that is throwing cylinder number 3 misfire and it feels and smells like a rotten egg no exhaust coming out did you replace cats or do straight pipe either way I need to keep O2 sensors I believe?
Don't know if you have seen this or not. I haven't had time to check out lal the videos and figures you could point me in the right direction. No sooner than I got my Actuator door replaced than my warnign for LEFT REAR DOOR AJAR came on.... research leads me to believe it coudl be a wireing harness due to faulty design... That said I haven't a clue how to dissasemble and repair. doyou have any videos that demonstrate how to take off a door panel or what not to get to the connecting wire harnes.
I've got a 2004 Ford explorer sport Trac XLT 4.0 I changed the spark plug on the passager side the one all the way to the back of the motor I think it's number 3 cylinder , after changing the plug it's still spitting and hasating let off gas and slowly give it gas it runs a little bit better anyone know what the problem is I sure could use it thank you
question regarding clogged cat, while looking in the engine of my truck (ford e350 05) I notice that driver side was not as hot as the passenger side, (I was able to touch with my hand and seems just warm, the truck has a misfire and no power, can a clogged cat could cause this?
It makes sense if no exhaust gases passing through the cat heating it up, it is going to be cooler than the other cat in which gases are passing through
Was wondering if you can help me diagnose a problem I'm having. On my way home yesterday, my '05 Expedition 5.4L just stopped accelerating at 20mph and would rev high. Wouldn't go above 20mph in drive, so I had to drive the rest of the way in 2nd gear. Is this a transmission or catalytic converter issue?
gilbert larrasquitu - Transmission was going bad. Had to let it go because apparently there was fuel leaking into the engine as well. Would've cost me over 4 grand to get it fixed here in the D.C. area.
Christopher Mark I have the exact same problem. Just had phaser lockouts installed along with vacuum assist repaired. Paid the hefty bill, got 2 miles from dealership and experienced the problem.
yeah i had had that on my 97 ford explorer, the spark plug was arcing too the block however it still misfires on idle i'm suspecting from what i've watched that it's the catalytic converter. will check tomorrow
blosom2315 Cylinder 5 is the only one that popped a code being the worst cylinder but multiples were misfiring on acceleration on that bank. You have to remember the gases are collected in a manifold so in essence #5 gases are the last in line to go like a crowd leaving a game and they all have to funnel through the exit door. So the other cylinders may have been able to pass some of the exhaust gases out of the cylinder but then those gases built up pressure in the manifold now there is no chance #5 is getting its gases out therefore they stay in the cylinder and severely dilute the air fuel mixture and misfires ensue.
hey pal, just bought an 08 Grand Marquis Ultimate Edition and the traction control disable button doesn't do anything. Do they commonly go bad? I'm sure I'll know what's wrong as soon as I pull off the dash trim and check powers/grounds
Come to Boston on your next tour! I got a 2007 f150 5.4 , truck started shaking at idle after a transmission rebuild, aamco says it’s not transmission or converter, I say bullshit . I know my truck . One day it shakes hot then cold , in Park and neutral one day then reverse and drive the next , it’s nuts , I hear a noise when in park , idle I rev rpm to 2000 and I hear a noise coming form floor . Near converter/flywheel. Any thoughts from anyone?
Thats happening to my is300 it looses power when you try to accelerate and makes that noice when you step your foot to the accelerator Where should i take it to get that checked out

Thanks for this video! My 2003 explorer had the same issue and this vodeo diagnosed it perfectly from the loss of power to bad shifting. Like a new truck again!
sir, your diagnosis the most right direct procedure ever.
It has to do with your training and devoted effort at Ford.
thank you.
Great insight into a plugged cat and how the engine responds to an abnormal situation.The baro reading was an eye opener.
Great tip Brian. I have gotten so used to using my backpressure gauge set or an infrared thermometer for restricted cat diagnosis.

thank you so much for this tip, PO402 just came on my FORD Edge 2019
The owner learned a good lesson for us viewers. A simple scan/diagnosis would have been cheaper than throwing new parts at it.

Check this out ..
If it has burnt out the cat , And by the sound of it being broken up inside the metal housing it has . Then how would it become stopped up per say and restrict the flow output ? Unless it has pushed the cat material out and into the muffler? I understand that is what its doing. With the misfire at the cylinder .

So I'm getting ready to get all the parts together if you are coming through oregon at all, we run a full service shop, air, lifts, etc just saying lol
I'm getting an "intermittent" P0430 2014 Ford Flex NA.
*Injectors ohm out at 14.5
New plugs, coils and cleaned Throttle body.
*Baro is rock steady 103
*Downstream o2's both sit at . 83 volts.
STFTR1 Is almost a solid line.
STFTR2 has a little wiggle to it.
Today I did a KOER Test and it came back with a P1101 MAF code, so I put in a fresh air filter, and tommorow with CRC the MAF Sensor.
The acceleration seemed held back up to 6k but after that it gets with the program.
Any insight to this data is much appreciated.
I've replaced timing chains, guides, tensioners, plugs, coil packs, injectors, fuel filter, crankshaft sensors, and Vct solenoids. Truck runs better with the vct's unplugged but still runs like crap. I don't get it. Are my cats plugged. I have rough idle, no power and can't tow anything

I have a 2013 f350 with 6.2 in it. Getting same both codes. But i erase them n they come back when i run it like 300-400 miles. What can it be
Quick Questions -
Background Info - 2009 F150 4.6L 3V, Automatic Transmission, 58K miles, I drive in tropical weather all year long (outside temp is never over 90eg or under 60deg) ... I basically use regular unleaded gas all year long except for three times a year When I run a tankful of 92 octane.
I have tried several fuel system cleaning products and methods to keep my engine fuel tank and fuel delivery system in top notch shape. None of which left me feeling that anything made a noticeable difference except for the BG 44K that you recommended.
After using BG 44K I immediately noticed that my MPG numbers fell drastically. From 17MPG to 12MPG and it now averages about 13MPG.
I suspect that the 13MPG is the true number because I backed that up twice with actual gas tank fill up gallon/miles numbers. Really close to 13MPG.
My first question - How can i get those MPG up?
I don't ricky road rage race my truck but have had it up to 100MPH once or twice since buying it new. I'm just an old truck guy that takes exceptional care of my vehicles and don't ever abuse them.
I've already done the FOMOCO sparkplug and coil change, trans filter/gasket and oil change with FOMOCO parts (and I replaced the trans bulkhead adapter while pan was down), replaced high quality air filter, Clean fresh engine oil is changed every 4000miles on average (I've only used Mobile 1 or Royal Purple oil from day one). I check my truck monthly for any trouble codes and have no codes listed or stored. My upcoming next planned maintenance is lubing the drive shaft splines with FOMOCO PTFE grease. I don't have any oil/fluid leaks. Compression is normal across all cylinders. All coil packs are good to go and within normal readings. Pulse width is normal. Acceleration is immediate and smooth. Cruising speeds and ride is normal.
Second question - Will adding second can of BG 44K help increase MPG or even make a difference?
Third Question - Am I missing some mechanical process or step to help get the MPG back up?
Appreciate any advice and or recommendations. Probably is what it is but would like to squeeze a little more MPG without losing power availability and drivability. Thanks ahead of time. Rick
It’s been six years lol You mind sharing any feedback and or thoughts for the next weary 09 owner experiencing similar issues? The code I struggle with is small evap leak P0442. One shop thought it was canister purge but comes and goes. Another shop said it shouldn’t effect anything noticeable. The fuel inlet is cleaned regularly using the funnel. I did the fuse relocation kit for fuel pump as I noticed min was showing signs of excessive heat. For some reason when my truck gets to below half a tank it seams more responsive with noticeable acceleration (similar to when you install a new battery and are performing relearn process). Also my ambient air temp reading on the dash is very inconsistent. I’ve seen my barrow numbers and open/closed loop jump around watching live data but i’m still trying to educate myself on reading fuel trims.
What's your take on Cataclean? Do you think it helps to remove some build up if your cat isn't in a failing state? I haven't gotten a code, but my car just sounds a little different. Thank you for all of your videos and tips.
Your the man bro thanks for your help always
I have a 2005 f150 5.4l and live in california. What happens if i add a non complaint california catalytic converter to my truck? Will it still pass smog?
What if I have the same symptoms but the baro reading looks good. 29 inHg (30 inHg with acceleration) in Chicagoland area.
Ford tech. I'm currently getting an intermittent p0420 212k on my 05 no other codes, and does not have anywhere near that low of power. My engine has been more lively. I don't have any other codes. By any chance the cats are just old and in need of a change or something is causing them to fail? I would hate to just throw new cats just to have them come back 6 months to a year later. Your input would be greatly appreciated.
P0420 code is a air fuel ratio code. My stock 3v 5.4 has 260k miles has gotten that code for bad spark plugs(computer leaned the tune) also plugged fuel filter(computer leaned the tune) code went away after tune up.
Just noticed this is recorded in Morton Illinois. I lived there the past two years lol. I’m experiencing the 430 code and cylinder misfire

Hi did you find out what was wrong?
I just recently fixed my right hand side exhaust manifold and now I'm getting a p0420 code on the right hand bank. Do you think that the exhaust leak on that side over the course of 3 years would have had anything to do with it?
I have 3 cats & removed one for sounds affects, I also have a cherrybomb m80 as resonater & the rest straight piped, do you think that me removing 1 cat is causing a p0420 code on my car, I has all this done a year ago & this is just now happening
I'm having an issue with a 5.0 f150 with brand new cats. Both are plugged again in less than a Month? Pain in the butt.
Brian... do you have a source on where to get a 2008 F-150 XLT Catalytic Converter Bank 2 Driver's side?. My Brother-in-Law has his own shop, and he was just quoted $1,055. Wow... Any sources would be much appreciated. Thanks...
My 98' 5.4 2V Expedition keeps blowing of the larger DPFE hose and there's a lot of hot exhaust coming from it . and also yes , if I floor it from a stop it will just stay in first even though it shifts fine through all gears under normal acceleration .
+joseph bourdeau yup your cats are plugged
Thanks for your reply your videos are really helpful . I did the mallet thing and also loosened the flange at the manifold and drove it around , It ran worse at low speeds but above 50 it found its legs ! I guess because it forced the pipes apart enough to relieve the back-pressure . I know I cant drive around like that( it sounds like an airplane) but at least I know what the problem is . Thanks again !
Thanks . I'm pretty sure what burned /clogged it up too . I had a leaking head gasket and a cracked radiator and overheated a couple times . Baked antifreeze in there , plus it's all broken up . I ordered a complete California direct fit assembly . I have since replaced the radiator and successfully sealed the head gasket with Prestone's new three part kevlar head gasket repair .
Brian I just had a P430 code. It's an 04 5.4 was 173k miles. No performance issues. Can anything other than a bad cat be causing this code?
I have an F150 ecoboost and keep getting a P0430 Bank 2, sensor 2. Can I just replace that sensor?
I had the loss of power issue, the occasionals rattle on start up, and the P0420 code to boot. When I pulled the cats off they were perfectly clear of any obstruction. Can the cats material be bad, thus throw a code and therefore electronically restrict power even though theyre not obstructed?
Also do know exhaust after cats can get clogged
Im on western ky ..i have a 2012 explorer xlt..i think im having cat issues..cylynder 6 and 3 misfiring. Loss of power shuttering hard shifts idles rough and low. Is this signs of a bad cat converter?
I have a f150 2015 and my sync up drive shows p0420 and the truck have the same noise, I went to the dealer and they refuse to replace the part as a warranty cause the check engine light isn't on. What can I do
My cats have 230k i get a misfire under load on cylinder 3 and a low threshold on bank 2 ive already replaced alot of parts should i bite the bullet and buy new cats
Great stuff thanks
Will it hurt to cut my cats out on my 05 4.6l f150?
My 2021 f250 has a
11k on it and keeps getting po430 and 420 codes and my dealer won’t warranty it, I’m gona have to replace the cats my self
Excellent diagnosis!
4:15 sounds and acts just like my outback. going to check the cats tomorrow or the next. - straight pipes woo!!!
wow I finally found it I was the same problem man hey do you think a 2005 5.4 will fit my 2004 5.4
THANK YOU
RUclips gave me an ad for CataClean at the beginning of this video first time I watched it - LMAO!!! Nice try - NOT happening! HMU if you do another one of these road trips, Brian, especially if you come to FL!
Can you check a cat. By temp. Inlet vs outlet ? Have an 06 4.6 triton that is running bad no power but with no codes .
John McCarthy . I have that similar issue on the same truck and year of truck
Yes infrared therm. Around $50 at auto parts store
You can get one at harbor freight for $15
I think this could be my problem on my 04 f150 5.4, but there's no rattle or sound like that when driving, just a huge loss of power second gear. I'm am getting lean bank 1 and previously , cylinder 5 and 6 misfire codes.
did you replace the catalytic converters or cut them off on your V for I have a 5 for 2001 F150 that is throwing cylinder number 3 misfire and it feels and smells like a rotten egg no exhaust coming out did you replace cats or do straight pipe either way I need to keep O2 sensors I believe?
Hello,
You said you was in southern Illinois. Where was you at .
Cool again good information keep up the good videos loyal watcher
Have a question I’m a five year Ford dealership technician looking to buy my own idsWhat would you recommend send me a personal request
Does sea foam work when sprayed directly into the plug where the o2 censor is?
Remove the o2 sensor first
can plugged cats cause a car to run alil hot?
Yes they can but they'd likely cause poor performance before that
I have a Ford exp it 5.4 and has no horse power and it got 4 cal and I don't know what to do
What about the catalytic converters on a 2007 lincoln mkx AWD?
Great job, what do you think caused the failure i have a 98 expo and have not had to replace cats yet.
Great job
probably no valve guides left.all that back pressure will wipe them out.
Can you up load a video how to change transmission flui on 2007 ford expedition thank you
+Pedro Hernandez I have many videos on that already search 6r80 on my channel
Oem cats better than direct fit aftermarket or no?
big time.
Don't know if you have seen this or not. I haven't had time to check out lal the videos and figures you could point me in the right direction. No sooner than I got my Actuator door replaced than my warnign for LEFT REAR DOOR AJAR came on.... research leads me to believe it coudl be a wireing harness due to faulty design... That said I haven't a clue how to dissasemble and repair. doyou have any videos that demonstrate how to take off a door panel or what not to get to the connecting wire harnes.
Can bad catalytic converter cause multiple misfire?
yes
I've got a 2004 Ford explorer sport Trac XLT 4.0 I changed the spark plug on the passager side the one all the way to the back of the motor I think it's number 3 cylinder , after changing the plug it's still spitting and hasating let off gas and slowly give it gas it runs a little bit better anyone know what the problem is I sure could use it thank you
question regarding clogged cat, while looking in the engine of my truck (ford e350 05) I notice that driver side was not as hot as the passenger side, (I was able to touch with my hand and seems just warm, the truck has a misfire and no power, can a clogged cat could cause this?
It makes sense if no exhaust gases passing through the cat heating it up, it is going to be cooler than the other cat in which gases are passing through
Was wondering if you can help me diagnose a problem I'm having. On my way home yesterday, my '05 Expedition 5.4L just stopped accelerating at 20mph and would rev high. Wouldn't go above 20mph in drive, so I had to drive the rest of the way in 2nd gear. Is this a transmission or catalytic converter issue?
Christopher Mark did you find out what it was?
gilbert larrasquitu - Transmission was going bad. Had to let it go because apparently there was fuel leaking into the engine as well. Would've cost me over 4 grand to get it fixed here in the D.C. area.
Christopher Mark I have the exact same problem. Just had phaser lockouts installed along with vacuum assist repaired. Paid the hefty bill, got 2 miles from dealership and experienced the problem.
Bad spark plugs will do it too!
yeah i had had that on my 97 ford explorer, the spark plug was arcing too the block
however it still misfires on idle i'm suspecting from what i've watched that it's the catalytic converter. will check tomorrow
just out of curiosity why only cylinder 5 it seems like it would be multiple cylinders on bank 2.
blosom2315 Cylinder 5 is the only one that popped a code being the worst cylinder but multiples were misfiring on acceleration on that bank. You have to remember the gases are collected in a manifold so in essence #5 gases are the last in line to go like a crowd leaving a game and they all have to funnel through the exit door. So the other cylinders may have been able to pass some of the exhaust gases out of the cylinder but then those gases built up pressure in the manifold now there is no chance #5 is getting its gases out therefore they stay in the cylinder and severely dilute the air fuel mixture and misfires ensue.
makes sense, thanks for the explaination
It's because he's the last cylinder on the engine in front of the engine
What obd tool did you use on the vehicle?
Ford IDS
Oh awesome I would have try it out!
@@elijahtaboy No OBD2 is 1996 and newer and he wasn't asking about that, he was asking about what scan tool.
@@ericschaefer7378 lol that was 3 years ago. And we are both wrong. It's 1993. I know because i have a 92 f150 and the 93s have obd2
What is bank2? Is that the front?
that is the 5,6,7,8 driver side fuel injectors, plugs, cops, ect. bank 1 is the passenger side.
hey pal, just bought an 08 Grand Marquis Ultimate Edition and the traction control disable button doesn't do anything. Do they commonly go bad? I'm sure I'll know what's wrong as soon as I pull off the dash trim and check powers/grounds
brakedd The switches never go bad that I have experienced.
FordTechMakuloco I took off the dash trim and the switch was unplugged. I wish all fixes could be that easy.
My 07 F150 has no codes but has to have a plugged cat or two. That thing just doesn't have any power none lousy gas mileage also
And I can't find a decent Ford mechanic that knows how to diagnose like you do. So I suffer with 8 to 9 miles per gallon with that POS
Did replacing the catalytic converter fix your problem I'm having the same issue cylinder number 3 misfire loss of power
Come to Boston on your next tour! I got a 2007 f150 5.4 , truck started shaking at idle after a transmission rebuild, aamco says it’s not transmission or converter, I say bullshit . I know my truck . One day it shakes hot then cold , in Park and neutral one day then reverse and drive the next , it’s nuts , I hear a noise when in park , idle I rev rpm to 2000 and I hear a noise coming form floor . Near converter/flywheel. Any thoughts from anyone?
Derek Koster check your fly whel
I have an06 5.4 titan nothing but problems with the whole truck buy a chev $ 900 just 4 a tune up with those FN plugs probably phasers next grr
My cat shouldn't be plugged I use 91 for the life on the car I'm at 150k
I have a 2013 Ford Taurus with a code p0430 check engine light on but sometimes it turns off then few days later comes back on again any idea ??
bad cat
Thats happening to my is300 it looses power when you try to accelerate and makes that noice when you step your foot to the accelerator
Where should i take it to get that checked out
