Expert:  MR. FIX IT replied 8 years ago.

your pcm might be bad (the computer)
did all this happen at the same time if you have all thoses codes on the transmisiion you got more than one sensor tripping

heres a list of possibilitys for the missfire

  • Faulty spark plugs or wires
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector(s)
  • Burned exhaust valve
  • Faulty catalytic converter(s)
  • Stuck/blocked EGR valve / passages
  • Faulty camshaft position sensor
  • Defective computer

and the only thing that links the two together is the computer try taking one from aneather car and just testing it and see what happens but thats what its sounding like

im sure you know whatthe codes mean but if you need i can tell you what they all are

Customer: replied 8 years ago.
is it the engine computer or the transmission computer can you be more specific and all theses codes poped up at the same time
Expert:  MR. FIX IT replied 8 years ago.
the engine computer and the transmission computer are the same computer it is the pcm (protective controll modual)
Customer: replied 8 years ago.
so if its bad can it still be able to read errors
Expert:  MR. FIX IT replied 8 years ago.

yes, if its bad it will give you the codes.

when they go bad they send false signals to the the parts of the car that controll how it runs causing it to act up and giving other codes
