hello,
i am having issues with the check engine light which keeps kicking out the CPS code p0340. i have done research on this problem and most people point to a bad alternator causing RFI feedback which is disrupting the sensor. this weekend i purchased a new alternator and CPS and am still getting the check engine light with the same code being thrown.
the car starts up just fine but when i accelerate, it struggles. it feels exactly like the firing order is out of sync. unfortunately i have double and triple checked the firing order to ensure this wasnt the case and still having the same problem. i did notice that the input from one of the coil packs to the PCM not solid but wasnt sure if this would cause this code to be thrown. i would think that i would get a miss fire code if the car had issues with the plugs or coils.
the car has 50k miles on it. any help or guidance you guys can provide is greatly appreciated.
thanks!
