Having some trouble with a 1998 GTS, Several DTCs stored, an entire list acctually. While driving the car will randomly start running rough, check engine light will start flashing very fast, no ryme or reason or consistancy, except one day it did it every 60 seconds on the nose, just one day, otherwise its random. As soon as the key is cycled, engine runs great, I can do it while vehicle is moving without even turning engine off completely. It will never completely die, just run rough.
P1388-Auto shut down relay control circuit.
p0202-Injector two control cirucit.
p0201-injector 1
p0209-injector 9
p0204-injector 4
p0205-injector 5
p0206-injector 6
p1282-Fuel pump control circuit.
p0207-injector 7
I have had circuit codes for all 10 injectors. Obviously the injectors appear to be on the ASD relay circuit. If that circuit fails I am expecting to see the injector faults, just curious if anyone had seen anything similar or had an opinion? I did do a wiggle test on the wiring harness near the PCM, not really much luck. I am kinda leaning twards a problem in the PCM, maybe, IDK? any ideas? Paxton supercharged and weldon fueling system if anyone thinks it would matter. Thanks
