How can I test the coolant temp sensor?What is the PCM, and how can I test it?I have fire to the plugs, it restarts sometimes, have to feather the gas pedal, when it does start, it blows black smoke and misses until you get the r.P.M.S up. If you keep the rpms up and don't put it in gear, it will run for a while. As soon as you try to let it idle, it dies, or if you put it into gear without power braking it, it dies. When it very first started messing up, right before it would die, it smelled like catalytic converter was stopping up, and the smell of gas also.I have no access to the scanner you are talking about. What does or is the scanner gonna tell me, or do also?
