Hey I'm back, I watched this vid in the morning and I'm just coming back from the test drive. 25 years of gunk will really make an engine seem weaker! Truck runs smoother and is more responsive. Thanks for making this video!
Man I think this is my exact issue; somebody linked to your video from a forum and your explanation was incredible, THANK YOU! I was initially chasing down what I thought was a bad / leaking injector, and found that the port on my throttle body was completely plugged like you described. I'm gonna go through the whole EGR system like you mentioned and I bet that will solve it. Appreciate it!
If i may ask , what exactly was the truck doing , now that you said you were thinking a leaking injector im curious cause i did solve another issue with these 90s model tacomas but i havent had a chance to make an in depth video of it yet
Yeah the main issue for me was on startup after the truck had sat overnight it would have a rough idle for 10-20 seconds. It would then seem to “burn off” like one cylinder was the problem, and then it would smooth out and run totally normal. It would blow a little gray smoke on startup while it did this. Never did it on normal or warm startup, only if it had sat 12+ hours. But when looking into it I found that my throttle body was full of gunk like you mentioned. I just got the EGR vacuum part and am going to see if that helps.
I just wanted to personally thank you bro, you definitely know your stuff and my PO402 code was definitely because of a dirty sensor so you saved me a bunch of money!! And to everyone else, LISTEN to this man!!!! 🤘🏻😝🤘🏻
I got a 2k taco a few months ago and use it daily just local but midrange it’s terrible, starts right up, goes as well as can be expected when pinned but it’s dead in the middle pedal area, I can’t wait to tear it down now I finally have a day off, thanks for the video
How do you even clean out the Egr valve on this model? I'm looking at it on my Tacoma and in pics of the part online and I don't see any of the typical Egr openings where you'd even see carbon buildup or whether the valve is sticking or working etc? No visible moving stem from what I can tell. Great video. Just got the 401 code but my truck idles fairly smooth. I sprayed gumout into the intake today while revving it. Actually seems like it lowered my idle just a notch and it's running. A bit smoother, less knocking & few more horsepower. Threw in a can of sea foam and some 91 gas. Cleared the code and drove 40 miles at speed. I feel like the modulator is prob the first thing I'll try if/when the light comes back on. Get a cheap one on Amazon. I checked the filter inside and it was pretty gross. Could not remove it how you did...it was brittle and tight... and as I pinched it just peeled off the top shreds so I left it alone.
What would you recommend for the TP sensor cleaning? Can I use Throttle Body Cleaner, or better Electronics Cleaner? I have a different car (2001 Saturn SL2), but also P0401 comes back like after 30 mi. I found many good tips on that code in your film. Thank you.
I'm actually quite impressed with your Toyota knowledge nowadays. I am glad I don't have to learn this stuff because I drive old carburetorated truck with no computer, if I didn't though I wouldn't know what to do. Haha..
Just throwing you some love for the good vid. I have an 02 lancer and can't find anything more like mine. My Modulator and solenoid are separate. My Modulator has 2 hoses that come from intake side. I can blow in one easy and the other has resistance. Off one of the 2 hoses , there is a T which goes to electronic solenoid that controls egr. I'm not exactly sure how the Modulator is suppose to function. Seems like I shouldn't be able to blow into one side, but even then the solenoid would be shut when needed. So this Modulator technically doesn't need to shut completely , I'm assuming that it shuts during throttle forcing the vacuum through solenoid to egr . My egr flutters and seems like it should open and close better and I feel like egr probably isn't opening very much but I'm no expert at all. Just hoping this is the little culprit.
I don’t have any codes but I did have a hella dirty fuel filter that looked like mud. Swapped all spark plugs and pc valve. Cap and rotor air filter and truck still feels very sluggish. You think even with no code cleaning that might give it a little better response.also nice video.
I have a 2001 with the 2.4 would I be able to just replace the EGR and drive the truck right after or does it require some kind of vacuum. A shop told me they had to vacuum some lines after I replace the egr but they wouldn’t tell me exactly what had to be vacuum so kind of skeptical.
It depends on if the egr valve is actually bad , they rarely fail , but if somehow it has failed cances are the egr passageways are blocked up with carbon and they will need to clean them out , does your vehicle have the vacuum modulator thats mounted over the egr valve like on mine should be a disk looking object with 3 small vacuum lines plugged into it
Do you know where I can get a “power steering air control valve” for my 96 Toyota Tacoma. I’ve tried Autozone, pep, o’reillys and so forth. Or any parts from Lexus at ay be compatible (open for the comment section) thanks in advance
Hello, at driving 65 mph for about 10 min theres a knocking noise, I changed the EGR, what it might be? I thought bc the EGR WAS STUCK CLOSED but it wasn't any advuce
The check engine light being off is cuz the battery was disconnected... not that it might actually be fixed, but I've literally changed every hose, sensor, valve and anything related to the egr system and I'm still getting a engine light, I literally have done EVERYTHING even remotely related to egr and still this damn light comes back, I do not get it
Ok so my 2000 toyota tacoma 2.4 idles a little rough but hesitates upon acceleration so those 3 hoses on the top of the intake yeah mine are removed and plugged and I don't see the egr so....... could that be the issue?
Your truck does not have an egr system so it could be a Dirty mass air flow sensor , dirty throttle body , or faulty iac , most likely all of the above
I have code p0401 code and my truck hesitates running in morning when cold , when put in gear it moves 3 feet then stop , 3 or 4x , sound like trans. disengages to eng. only happen in morning. Please help.
Once you remove the vsv you can use a 9v battery and a couple pieces of wire to activate the valve once open you can spray carburetor cleaner through it , although it might aleviate the issue for a short amount of time i highly recommend replacing the vsv all together , the chances are if the vehicle has over 100k on it the valve inside the vsv is most likely scarred and worn down or the field winding that opens the valve has become weak over time ,
Hey brother, I cleaned out the egr port as well as the throttle body. Everything seems to be hooked correctly, but it’s idling high. What can cause that problem? Thanks
your vehicle should have an egr system , at least according to everything i have read , unfortunately without being able to look at it i probably wont be much help , as far as i know they didnt move to the design without an egr system until the second gen tacos , is this a truck that you have had since it was new or did you buy it used ?
I like that you covered multiple, possible related components and issues to check and/or fix.

@@joelchristopher190 how did it go?did you replace the EGR valve and clean the tube that goes from the Exhaust?
Great video! This helped me a lot on my pops 95 Tacoma 2.4L. The carbon was so gunked up inside the intake manifold.
I'ma try this out nervous but this gave me some guidance an confidence
No freakin way! I've been running around this problem for the past year and a half! Changed the whole egr valve and everything. Thanks for the help!

Good man you have a Bauer drill I love it.
Hey for a cheapo it does a great job lol
Thanks for the video, very informative
Do you recommend buying OEM egr vacuum modulator and egr or generic brands ?
Im running a generic and it has been fine for years
@@TheRandomMechanic thank you 🙏🏼. Today I bought my son a 96 Tacoma. Has the P0401.

I ask because if that isnt working , and if its the original id bet you money it isnt then thats why your egr valve wasnt working

Have you looked one up for a 4runner ? Unfortunately i have not been that far into my power steering yet besides rebuilding the power steering pump ,
Cool fix. Thanks.
Hello, at driving 65 mph for about 10 min theres a knocking noise, I changed the EGR, what it might be? I thought bc the EGR WAS STUCK CLOSED but it wasn't any advuce
Knocking usually is a very bad thing , does it make the same noise if the truck is out of gear or only when you are moving
@@TheRandomMechanic it literally makes that knocking at that instance none other, and a semi rough idle may I add, and same engine code po401
@@michaeltinajero8014 egr stuck closed is good you moron you need a new engine is what you need
Hi !
I do have a question, what's torque specs for egr valve and pipe ?
i just tighten them by feel , seems to do just fine
Ok thanks a lot !
I have same problems with my truck and it was the one close to the canister. Problem solved
How much do it cost?
Did you have any intermittent stalling and no starts?
No but it wasnt far off from acting that way
Great vid broh...

Sounds like youve got a few things going on , what all have you done so far ?
How do you replace those skinny hoses, where can I find them
They just pull off , you can buy them by the foot at your local auto parts store , they are called vacuum lines
@@TheRandomMechanic ok thanks alot !
Hi !
How do clean the VSV up !?
Once you remove the vsv you can use a 9v battery and a couple pieces of wire to activate the valve once open you can spray carburetor cleaner through it , although it might aleviate the issue for a short amount of time i highly recommend replacing the vsv all together , the chances are if the vehicle has over 100k on it the valve inside the vsv is most likely scarred and worn down or the field winding that opens the valve has become weak over time ,
Thank you so much, I really appreciate it !
Hey brother, I cleaned out the egr port as well as the throttle body. Everything seems to be hooked correctly, but it’s idling high. What can cause that problem? Thanks
Could be the idle air control valve , did you clean it while you had the throttle body out ?
Also make sure the throttle is completely closing , the cable may be set tighter than usual
Cool , throttle cable is good. I’ll check the idle air control valve tomorrow. Thanks !
How long does the job take? Anyone know?
Thank you
You can probably get it done in a few hours , its really not as bad as it sounds
I’m getting all the related codes but my 01 2.4 has no egr system. Any clues?
your vehicle should have an egr system , at least according to everything i have read , unfortunately without being able to look at it i probably wont be much help , as far as i know they didnt move to the design without an egr system until the second gen tacos , is this a truck that you have had since it was new or did you buy it used ?
I bought it used 11 years ago. There’s definitely not an egr system. There never was. I called Toyota and they confirmed it.
@@Toddtoddy78 thats very odd , especially if the truck is throwing the same trouble codes
