my car is running really ruf, and after it heats up it barley idles, I have had my air pump disconected because it broke, and I was told it was fine to leave it off, but now I'm told that me EGR valve is most likely clogged with soot, and thats why it runs like it does. any help?? thanks guys!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

If you unplugged the airpump and you are using a stock ECU (or a rechipped stock ECU), you'll need to raise the idle up to around 1100 rpms for it to be smooth.

this seems to be the problem

 

Thank you alot guys, just to ask again in a bitt different manner, The car ran fine for around a week with the pump unpluged, then it started in with this issue, and it shows that I maake boost but the car just does not wan to go anywhere, and it will not hold idle.. And do you know where to find the egr valve? Thanks Again!!!!!

 

EGR is on the left side (if standing in front of the car looking into the engine bay) side of the LIM.

 

here is a link of a "how to" in replaceing or removeing egr:
