Well i had some coils go bad on me a few months ago, so decided to go ahead and replace both the coils and the plugs. since then she has been running like new, but a week or two ago i noticed that it was starting to run a little rich like i was sitting behind an old car when i was at a stop, but still runs just fine. All of the connections seemed to be good so im not really sure were the problem is. Any help is appreciated

 

Doesn't this car run rich in general due to the stupid emission mods which seems to be the cause of most of our engine probs?
