Could a rich condition cause...
higher operating temps in stop n' go type driving? I know my car is runnin' rich (had some tuning done) and I will correct the problem. What I'm wondering is this; I had the PCM re-tuned (fan temps lowered was part of it) and, w/ the a/c on or off, it definitely runs a bit cooler on the highway BUT in city driving it almost runs the same temps w/ the a/c on or off. Before the re-tune w/ the a/c off the car always ran cool (180-190) regardless of city vs highway driving. Now, in stop n' go stuff I'm seeing temps climb to 209 w/ the a/c off yet as soon as I hit the highway it cools right down. I'm aware of all the cooling system checks (not the problem), the problem lies w/ the re-tune. It's weird, now the car runs almost cooler w/ the a/c on than off and it's a direct result of the re-tune. My thoughts are this temp problem has something to do w/ the rich condition.
Any ideas or educated opinions?
