So far all I have been able to do is find a CP9001 code reader. Looked at the 9145 on Amazon and it was $279. OK read the instructions ref. pluging the unit in and hed no check engine light. Instructions are,there is an electrical problem and need to consult the circuit diagnostics section of the owners manual. No such thing in the owners manual. One thing I failed to mention above is that while driving between 48 and 55 mph and you are not accelerating just cruising along, if you ease down on the accelerator pedel it starts to studder, you can gass it and it goes away. once you accelerate thru it and back of to that speed again than apply light pedal, it starts to studder again.? I am wondering if the TPS is the issue?
Almost forgot. I do have the service engine soon light when I turn on the key but it goes out when I start the engine.
