My 1990 mustang is idling like crap I have checked out jrinkers surging idle checklist but haven't gone through it yet because I couldn't find anything relating to my problem. I will go through it and actually check everything today. My problem is when my car idles at startup it idles around 1200 and comes down to 800 whenever it feels like it. But my rpms actually raise when i push the clutch in the come to a stop or shift?? It ranges from 2k-3,5k rpms when it does this. I pulled the codes I have koeo 15, 85 and koer 31 44 94. No catalic converters and the carbon canister was deleted. Any thoughts on what's going on?
