All sorts of trouble.
My 91 2.3L Mustang is running terribly. I replaced the Primary coil pack and it still doesn't fire on any of the coils ;secondary fires just fine on all coils, but not only when this happens my turn signals stop working and my heating and air quits. The car would be driving just fine until my engine warms up and then the Check Engine light will come on and all of my problems will start. I thought it could be the ICM at first but then I notice all of the other problems occurring at the same time.
