I am having a problem with diagnosing what is exactly what is going on with my 87 GN. A few days ago, my Scanmaster registered a Code 42, which is EST Failure.
While driving my car, the car will miss or backfire at WOT, so I am thinking that I have a bad coil pack that needs to be replaced.
The car also shut off on me 2 times, both times were when I was stopped at a red light, and when the light turned green, I pressed on the gas pedal and the car just died. I was able to turn the start the car immediately after this happened, and everything was fine thereafter. Again this has occured twice, and I'm not sure what the problem could be as far as this situation. Could this also be a symptom of a bad coil pack, ignition control module, or faulty ecm? I checked the connections to the ecm, and everything seems to be tightly placed with nothing loose.
Could you guys help me out with describing some symptoms that I would be experiencing if my car had a bad ECM, Coil Pack, or a bad Ignition Control Module.
I just don't want to have to spend any money on parts that I don't need to replace at this time.
All help will be greatly appreciated.
Thanks
