You can try to re-flash the PCm that's want gives you the codes, if that doesn't work you may need to replace it...
Is that something I can do with my Innova 3150 scan tool?
So if I remove the PCM Can it be tested at the dealer with out the car ? Should I try junk yard ( used ) one ?
Is the PCm you list the PROM control and is it built into the engine control module ECM
