no codes and no check engine light. it seems as if when i unplugged my water temp sensor it would idle longer but its acting so random i don't know if it is related at all. i installed a new coil and drove it for about 25 minutes so far it hasnt died yet , but i'm not holding my breath because it died once or twice just after i installed it in the shop at work. however i noticed that the intake manifold has been leaking oil since i installed new gaskets a few months ago and the oil was somewhat low, i don't know if it is related or not. i refilled the oil.
