How To: EGR Removal and Cleaning for Rough Idle Fix

It really doesn't bother me that much. I bag the absolute piss out of my car, so I don't expect it to run 100% anyways. Besides, it's only for the 2-3 mins after I fill up with gas then it goes away.

Hey Maxx,

You ever figure out what the problem was? I got this same problem and i'm unable to figure it out.... If you did figure it out, How did you correct it?

Thanks in advance
 
hbk2k1 u probly wont have one. Its directly behind the TB maybe u guys need this(attached pictures). im pointing behind the throttle body, by the ughhh intake manifold and the firewall. thats the top of it my fingers pointing.

Im still wondering if anyone has a smell related to the choking.

hey my car has been idling around 500 but lately we got hit will severely cold weather and the rpms would drop and almost stall then back up again. it would do this twice before settling at 500 again. this is during normal driving like when im waiting to turn left it would do this, at a stop light..does this mean my egr pipe is in need of cleaning? recent mod installed was the CustomMSP SMIC..help!!
 
I'll take some photos tomorrow morning, if still needed. You going to need a special torx wrench to take the valve out. Clean the plunger and the housing.

check out the pics. In my case, when i removed the solenoid valve, the plunger got stock to the throttle body. There was carbon build up.

Hmm... I can't seem to find the "special torx wrench" to take off the IAC valve... I have a torx bit set but the torx screw on the valve has a little nipple in the middle...

Anyone know where i can find the "special torx wrench" I checked sears and they don't have it.

Help...

BTW the original post for this quote is #97... It has the pictures also. I am still waiting on some time to do the EGR clean. But i figure this would be easier since its right in your face.
 
Sears does have it, thats where I got em'. I don't know the size, but the set will have the correct size.

Hey Im new to the site and am buying msp monday when you hit the clutch at like three four thousand rpm to just roll to a stop sign or what ever the car stalls is this just because of the turbo and to high of rpms or could it be the egr valve. the car has eighty thousand miles and im sure its never been cleaned. and how do you reset the pcm? Anyone who can help or has info let me know

if its the egr then your rpms will go crazy at idle and your engine will be close to stalling. i don't know what you mean by pcm but to reset the computer in the car u unhook the battery and put the lights on to drain any power remaining in the system and then connect everything back up.
 
I just replaced my EGR today (had cleaned it several times before); idles like new (well, mods aside....).

I personally think that cleaning the EGR is fundamentally a waste of time. IMO, it's much better to get a new/better designed one than to continue otherwise.

We'll see how long this one lasts though (aftermarket from Autozone - Mitsubishi solenoid, all made in Japan).

i agree. after i cleaned mine one time and seen the problem return after 1000 miles i bought a new redesigned one and no problems for about 30000 miles so far.
 
Thanks..I think its time to clean my egr..but why waste time taking it off to clean it when the only true answer to the problem is to buy a new one.

cleaning may help some cars but not mine. i now have 26000 miles on the new egr valve and no problems.
 
hey guys, new to the forum, my woman has a 2005 Mazda 3 with the 2.3L engine. she has been having some eratic idle issues and I was just wondering if the 3 has the same egr valve the protege had? any help would be great, thanks
 
Can someone please tell me where the IAC is on a 1.6L automatic? I cleaned my wife's 1.6L's EGR and everything is much improved but the car still idles a bit rough. I wanted to clean the IAC if only I knew what it looked like...
 
Question: If I can't get those 4 phillips screws out, is it safe to stick part of the EGR valve in a cup of carbon removing stuff?

I mean can i stick the whole boxed in part in a cup of that stuff and leave the top plastic parts out of the solution?
