How To: EGR Removal and Cleaning for Rough Idle Fix

[shane02pro5]

It gets pretty caked in there and actually needs to be scrubbed a bit to help loosen it. Best to put it in a vice or something for more leverage and try finding a phillips with the little tiny grooves on the tip to give you some more bite in the screw.

Also, what did you guys use to soak it in? I had a Styrofoam bowl and the stuff I'm using ate right through it, then I used a plastic cup and same result...

wth u using?

B-12 Chemtool...

use a metal cofee can or something glass. i used wd40 (the liguid kind) not the spray and i soaked it ovenight. i broke one of the screw heads so if its so hard to take out then you might as well break it and go to homedepot and get new screews. i had to.

ok so i have been having the idle/die at stop light problems like the first post says... i took the egr off and cleaned it with brake cleaner and a dremel with a small brush on the end... reinstalled it all and im still having the same problem... wat else should i try?

 

[Cellerator]

Did you reset the computer? If not, try that.
Other solution is if it is throwing a CEL, go to autozone and see if you got a misfire code, it could be a spark plug wire.

 

[SoonP5ismine]

does the piston in the valve move freely when you push it with your fingers? did you reconnect the power plug to it when u put it back on the engine?

Cleaned my EGR today and wahoo, no more CEL!

To get to the EGR did you have to remove the intake manifold gasket? Was just wondering, as just had my EGR valve replaced (apparently factory recall on the EGR 2002 P5)

The stealership touched me up for 290.00 dollars to replace intake manifold gasket!

woah, i didn't know it was a recall. nothing comes up on my car. its easier to get to the egr by removing the intake. they didn't want to have to work too hard, and get paid well for it. i wouldn't have paid a dime if it was a recall. all the work they did should have been covered.

LOL, if it's the gasket in between the EGR and IM, then yes but it's nothing special, made of some metal and fit right back on. It takes maybe 20 minutes to pull the whole EGR valve and put it back on. If it's elsewhere, I don't see why you'd have to do all that just to get to it. You take off the intake pipe and get a socket wrench underneath the throttle body to undo the bolts for the EGR.

That's what I thought, but I wanted some confirmation, Make matters worse they forgot to tighten the bolts for the EGR.........I am not a happy camper!

Post your location, I'll make sure I NEVER go to that State for (incompetent) car repair. HOLY F&CK

Be sure to print this last page or two and give it to the service manager!!!

Just cleaned my egr, great writeup. Those bolts under the egr where a PITA to get out, but i found an easy way if you don't have wrenches (which I did.... they were just way to big). Put your car in gear (with a standard) and push the car forward and back a few times, and then one big push and pull up the e-brake (before it rolls back). That way the engine is rocked forward a little, giving you that extra room to get a small socket wrench on there.

ok i read alot of this thread.

anyone see improved gas mileage?

 

[i12drivemyMP5]

You always get better gas mileage when important emissions control parts are not gak'd full of carbon. You're not gonna experience any awe inspiring miracle differences tho.

 

[Pmpkinhead]

I just did it again and my tanks have been giving me 23 to 26 MPG (averaging around 24). Still horrible as usual.

Could you spray Seafoam Deep Creep in the IAC and EGR..or would it be better to buy seafoam in the can and let them soak in it?
