I notice that just sometimes, the car idle high when started. When driving like this the car run hot and then the engine light come on. The guy told me the code that comes up is tell me that the car is running to lean or to rich. He also said it could be a vacuum leak some wear or a bad sensor. The question is what should look for to fix this problem, if anyone had this problem as well.
I have the v8 northstar and it idle high off and on after driving stop and go traffic for about a hour. It would go between 1100 and 600 with in the ride. When it do that I also notice that my temp g, move over to the hot side. Now say I pull over and turn off the car to do some thing and get back and start it up I will now hear the front dual fans race to cool it down and stop when the line is back in the middle. I would not hear or feel them come on any other time. I just want to fix this heating problem before is gets worse. What should I do first.
High idle is most likely a small intermittent vacuum leak or a sticking throttle plate. The fans running after re-start is due to heat sink; if you continued driving rather than stopping it would probably cool itself down. I'm not sure you really have a problem other than the idle and that doesn't seem serious yet.
