Okay, so my car has been a check engine monster throwing erratic codes. I clear them out with the Predator only to have them pop up again.

Unfortunately, there is no consistency in the codes. I'll get an insufficient switching, then a catalyst system below efficiency, air pump, then a L Gen Wire. Just no consistency whatsoever.

Somebody suggested that I might replace my EGR valve, that those tend to go out and it's an emmissions issue. What do you guys think?

 

what code is it throwing?

 

if it the code something like 400, my car does the same thing, and it make my car smell really bad, I change it out with ac delco, car dont have that burn smell any more.
