This worked great. I removed my plug ins to the PCM, sprayed the pins with CRC Electrical Connector Cleaner and used my air compressor to dry them out and clean out any debris. These pins were very clean anyway. Then I went to Lowes and picked up the weather stripping and cleaned off the old gasket material on the air filter case. I also vaccumed out the area where the filter goes. It is running much better. Thanks so much!!
Thank you for the vid… I might as well give all three a shot. Otherwise I’ll go back to telling the wife that I have to drive for a few hours to test, when really I’m going to play golf
My 99 started running a little rough . Then I was looking for a vacuum and moved the air box then cylinders 1, 2 ,3 ,4 codes came up misfire . I was at a loss ! I just saw your video and when this rain stops will certainly give them a try ! Thank you for your share !
update, my truck is a 2006 5.4 3v, i cleaned the plugs on the pcm but i feel replacing the weather stripping on the air cleaner was the trick that worked. cheap to do thats what worked for me. great video thanks!
Was yours pretty bad? Mine is 06 as well. If I hammer on it, it won’t go over 50mph. But if I ease off it, and ease back into it, it’s fine. Sound similar? Thanks man!
Different year: 2002 F150 Triton 5.4l. I replaced A/C and all hell broke loose. I had p0352 (second cylinder electrical issue) and A/C compressor would not run. Changed spark plug, injector, ignitor coil with no luck on p0352. Finally, after two year delay, I re-inspected the electrical connectors on the firewall for possible damage. I found that two of the pins in the bolt together connector were pushed back and probably not making good contact. I also found that IF I had a p0352 code the A/C compressor would not run. Every time. When I fixed the connector, both p0352 disappeared AND the A/C compressor ran. I am not sure of the reason for this. This was a key find and allowed me to finally fix both issues by making sure the connector was in good condition. If your not successful at first or only have a temporary/intermittent fix, examine the connector even more closely to make sure that the pins are clean, the gasket is not preventing full engagement, and that your connections to the ignitor coil and fuel injector are securely engaged.
At beginning i did not too much credit in the video. I replaced the coil and nothing changed. Misfiring and shaking and then i unplugged the ecm and clean with contact cleaner. Holy boy. Car engine light disapear and it looks there’s a turbo on my truck it’s fast. I bought the superchager one month ago and now i know the difference. Thanks
Wow thanks! I change out spark plugs, put sealant and weather stripping still had rough idol....cleaned and reseated the connectors and BAM! No more rough idle and cleared out check engine light. Thank you sir!! Now to fix leaky coolant problem 🙄
@@ryanruz9397 did you get your coolant issue fixed? I had to buy a new upper intake and have it replaced. The coolant was coming out due to a small crack by the thermostat housing.
That vacuum line that you're referring to with does it going to it that is the I guess you would call it the exhaust or the relief for your vacuum actuated hub locks for your 4-wheel drive you need to unplug that if you ever decide to use your four-wheel drive
So I bought a 2008 f150 with this problem ford said it was cam phaser problem we put in new phasers, timing chains, sensors and tensioners but had troubles timing the engine so we took into a local shop and they “fixed” it for $3,600 and the truck ran great for 3 months no problems I even took it off roading in some mud and worked prefect. Last weekend I took it out to our campsite and the truck stalled out. I drove it home with little to no problem and I took it out today for a 15 min drive to see what would happen and the check engine light came on and it the rev meter was trembling and misfires and it was shaking going 80kmh down the road and the knocking was pretty bad. We put in a code reader and it had the P0300 code. So next week or so we’re gonna replace the spark plugs and see what happens and try things to get it running so I can just sell it and be done with it.
Yes you are so right don't listen to the haters. I did these 3 things and the truck immediately started running correctly, check engine light off, the vacuum hose T's into the vacuum hose running horizontal directly above the one you have tape on. with a check valve between the 2. diagram on sticker attached to the plastic over the radiator. At least it is on my Expedition. thanks man!
I was told I need to replace both of my catalytic converters my ford 08 f150 is doing the same thing as ur on top of the smell of raw gas all day and it’s drinking so much gas. Check engine light on and it has a back misfire was cylinder 8 but all the plugs and coils have been change. Do you think the converters could be the issues
Thanks , what I did was let the air pressure out of the fuel injector rail started the Lincoln Navigator and the problem went away .. So yes you’re right it could be anything..
Check the pcv valve, it is located at the Valve cover, on the driver side if stuck open that’s the problem wen engine has multiple misfire and shaking at idler
Mine had a Huuuuuummmm noise at idle. Replaced the IAC valve and fix'd that. Still left with a slight misfire nudge as she idles. Whille attempt to unplug coil AND injector connectors searching the cylinder. Scanner w/live data isn't showing anything out of place other than a misfire overall in general not per cylinder test. The challenge is fun I guess.
mine is doing this intermittently, check engine light flashes and i dont get any codes. always at higher RPM,3k-4k 70-80 MPH. im going to try your tips thanks.
Thanks for your video ! I has same problem Bought the truck ! Start but when put on drive or back up it shake but when I drive around 20-30M/h it ok Press gas it shake again after that drive fine at 60-70 Light on need service soon Try to replace coil and spark plug later Thanks
What is the hose just to the right of the PCM thicker diameter, ribbed, curved back into cab, connects to a stiff metal line/pipe. I seem to have a leak from there into cylinder 4 which is causing my truck to misfire.
Coolant is probably leaking into the coil. You'll need to replace the boot, spring and plug and definitely get the leak fixed or it'll continue to happen. Easy way to check is after letting your engine cool down for a couple of hours pop the coil pack off and look down into your spark plug inlet. If there's any moisture, that's not good.
Where to reput the foam ? I forgot where it was. My truck did it today after a 2 hour drive in tye heat and a fresh oil change. Stopped at a stop sign jumped back on highway and stutter stutter check engine light flashes and then went away.
My uncles truck has this issue truck was running fine. But as he was leaving truck would shake we notice that one of the coils was loose and the bolt that holds it was broken off
I just replaced the cool! Sparkplugs! even the throttle body and it did run better ! But still have the misfire and rough idle when cold,,, it runs very nice once it's hot! But you can still feel the misfire and code on #4 cyl,, inevern eeset the PCM and nothing!! Next is replacing the temp sensor,,,
Unplug both of your variable timming solenoids they are located on the front of your valve covers and see how it runs you can run the truck that way but if this is your problem your cam phasers probably need replaced
my inlaws 2007 harley f150 5.4 started pulling. he found it that 3 cylinders are misfiring. he has never changed the spark plugs. never done a tune up. oil changes on time are questionable. they told him he has to rebuilt or swap the engine.
There are like 4000 things that could make this happen. I said in the video this is after you tried plugs, vct solinoid, coils, etc these are just some hail marries to try as a last resort. There is no difinitive answer with a 5.4L
Straight To The Point did this resolve your engine shake and misfire ? i did this and for a couple days it seemed to get better but still minor engine shake. but low and behold i got the p0303 couple days later and rough on slight acceleration and low power. i replaced vct solenoids like everyone says to do as well.
My 2007 Ford expedition is having the same problem it say in the diagnostic cylinder 7 misfired.im taking to the dealer because fews mechanic want to deals with it
Its actually felt along bottom and sides of air filter frame that holds AF and slides in. I used 3/8inch rubber car gasket sealer. Clean frame off good, cut gasket to size, remove the adhesive covering, snd attach to the plastic frame.
That’s not vacuum line you plugged there buddy, it’s your A/C system moisture drain. You better unplug that unless you want to replace your evaporator core because it’s been sitting in water.
You plugged it and it went away... plugged it to what? You said it went to absolutely nothing.. I feel if you would demonstrate the video a little better then people would see. We came to RUclips to watch a video...
Plugged it, not plugged in. As in capped it off. Like i said i don't know what it went to but ive seen them on alot of trucks. It might be a vaccum vent tube. Just something for people to try.
My truck dose the same an idle low then high an now has a odor like bad gas or something but mine is a 02 f150 4.2L having trouble finding much out about it an my engine light is on an when I got it checked all codes came up engine disabled an all that not shore where to start
You can order a whole set of coils here in the states for 40.00. They come from China but so do the oem ones that are called Motorcraft. Anyway. I paid 35.00 plus tax. Less than 40.00 for all eight coil packs and they been working great so far.
This is why I’m trashing my 2008 Ford -150 Triton STX, it is a pile of junk, I’ve replaced so much in it and it still runs like shit and dies at stop signs and red lights.
The Ford dealerships are incompetent and even deceitful. After having so many bad experiences with multiple locations I decided to start doing my own maintenance and to never purchase a Ford again.

What is the hose just to the right of the PCM thicker diameter, ribbed, curved back into cab, connects to a stiff metal line/pipe. I seem to have a leak from there into cylinder 4 which is causing my truck to misfire.
Heater core goes into the cab for heat. You're probably leaking coolant into the sparkplug well and shorting out the coils
