Dear, I have a big problem with my car. When I turn on the ignition, my fan starts spinning immediately. I have now changed that so it registers that the engine is getting warm, but then it doesn't cut out anymore. And when it registers, the engine tends to stall and is difficult to start. I have removed the AC and air pump and installed new sensors, and the IAC + ECM is new. The car is currently in the garage and they can't find the problem either. Maybe a short circuit somewhere in the wiring harness?
