I just wanted to know if the EGR valve problem known to happen on our TL affects the engine'S performance. I believe it does cuz if the flow is insufficient the engine cannot logically work at full potential. Before I had that problem I would not have a problem at least keeping up with my dad's 04' TL, but now he can definitly pull on me without a problem... i had an extra person in the car too, and my system in the trunk, but I believe the EGR valve problem (TCS/ABS/CHK ENG lights are on) is affecting my car's performance..

Let me hear your thoughts about that.

thx

Once the code is on, the computer automatically runs rich to save the engine.

It's not the actualy flow of the EGR that is hurting the performance; rather, it's the OBDII that is running it rich, trying to save the engine.

 

that would also explain why my car takes so much gaz

 

hmmm, i have all those symptoms!! how do i clean out the EGR valve?!?!?!??!

 

Um, 5,542 posts on AZ and you haven't noticed the threads aboout this? fsttyms1 has posted several DIYs about this.

 

ohhhhhhhhhhh, yea i have seen that thread. the one where he flushes the IM out with a hose. got cha thankss

 

Dats da one!

 

What you guys are talking about would be cleaning the EGR ports, not the actual valve.

 

alright so im doing this now. it seems to be a little more involved then i first thought. i think i need a allen head screw driver to get the front and back of the IM off. all i corrent? i also have to remove the intake and all associated hoses and stuff.

as you can see, i have never dealt with engine work before.

edit: when i took the top cover off, there is oil in the area below. thats normal right?

 

Yes, it's normal.

 

i gotta quick question. I have a 99TL 109k miles and get 25-27mpg. I cleaned my TB, do you think my EGR valves would be clogged up?

 

so that explains y my check engine...tcs...abs...and traction control light is on and my car been eatin gas like a mofo to???.....dam i dont have a shittin clue on what to do lol

 

i found fsttyms1 post about this problem and how to clean it here it is fellas

its in the second post

 

yeah, cleaning may help, but what i've discovered, my EGR valve wasnt too good, so I replaced, my mileage greatly improved, and everything is fine.

@cur@, are your cylinders misfiring? is the engine shaking?

 

how much do the egr valve run? and is it easy to replace?

 

n/m i just checked, wow, 170$!

 

in most cases the egr valve is good. its just the ports are plugged up and the computer is trying to compensate for it. Id do a good cleaning of every thing first and see how that helps. Typically a bad egr will get stuck in a certin positon (usually open) and your idle will get Really bad (it will run like you just slapped a big set of race cams in the car)

 

mmm....

 

actaully i should say it will idle like that, not run with the gains of a race cam

 

well, obviously But just the thought having aftermarket cams in my car makes me .

A company needs to step up and take on the task. I would get 'em for sure.

 

that would ALSO explain the funny idle!! wow... i cant believe i just found the source of all my problems

teknoking: yeah the check engine code was a cylinder misfire.. probably cause by the insufficient airflow that would make the cylinder overheat..

 

what a coincidence, my gf's 2001 Accord V6 is having this same exact problem.

fsttyms1: you said that in most cases the EGR Valve is good, and that i should just try to clean it out for her? How much do you think a shop would charge to do this? or anyone in houston willing to help me with it? I am mechanically inclined... So how hard would this process be on a scale of 1-10, 1 being a light bulb change and 10 being a complete engine swap/assembly.

 

on a scale of 10 this is a 2. its Very easy and only requires BASIC hand tools.

here are acouple threads on it, im sure the accord is very similar in design

do a search on the code p0401 or on my name here. there are many threads now about this and there are good diys on it
here is one from a 99

Could this be under warranty if the car only has 70k on it?

From the pictures..you just basically take the TB off and spray it down with carb cleaner correct? What part is the actually "EGR Valve" because thats the code it was throwing. I apologize for my incompentency but i just want to get everything straight before i take it apart. Thanks again.

 

the EGR valve is the weird funnel like pipe in front of the throttle butterfly. you cant really see it in the pictures of any of the threads, but its there.. hmm, i'll try to look for pics of an engine that it shows..

also, its not a warranty thing. the only thing covered til 100k is the tranny..
its RARELY the egr valve itself that causes the problem. all you have to do is clean out the egr hole in the intake manifold and unplug the battery for a while.. this clears the check engine light, and takes care of the problem..

 

you dont take of the TB and spray it down, you have to take of the Intake Manifold. the code P0401 is Insufficant Flow. it has nothing to do with the egr itself, but the ports that it feads teh recirculated Exhaust Gasses back into the IM.

the rusty piece circled is the EGR

 

My car has 48,530 miles on it. Do i need to clean it out at this point to prevent getting this problem?

 

I did it with less than 40k miles on my car, and they were dirty as hell.

 

dude thanks for a lot of the help. your badd ass.
