Alright so I’m down to 172 and 334 code. My egr seems to be functioning properly. I read a thing where you tap into the green hose with a vacuum gauge and drive the car should read 0 at idle and 0 at WOT. Now I’m not reading 0 at idle but reading 0 at WOT. The car isn’t running bad. Sometimes 1 out 1000 stops) acts like it wants to die when you come to a stop.

The CEL only comes on after driving it for a little bit then once you shut car off and back on it’s gone then eventually comes back on. I’m guessing the EVR is bad. But I’m not 100% positive Ive checked all the vacuum hoses no leaks. I’m starting to get frustrated cause I’ve cleared all the lights in the dash..besides this one. Can someone give me some steps to take on testing and checking.

So I’m starting back to square 1 pretty much and getting some other opinions.
