I'm curious - is there any part of the airconditioner system that tells the engine to enrich the mixture because the engine is under load? My AC went out a while back and I'm trying to figure out a rich running problem - I have done almost everything possible (list below) and am wondering if somehow the system that tells the ECU the AC is on is making the car think it need to make the mixture rich - Is that possible?

Would appreciate any advice.
