Hi, I read everyone’s post, and have seen some close problems to mine, my temp light is on, my car runs rich, and smokes, I tried running With ac but still stalls when going around block when I stop, (somebody said try that)I replaced Temp sending switch and sender, o2 sensor, mass air flow unit, s plugs, fuel regulator; I tried something to see if it’s the cold-start valve by Disconnecting cold start switch when hot and cold there was no change in the motor still ran rich? Anybody have a clue?
