code p0300 after tune
code p0300 after tune Hi
Appreciate all useful input.
I got a mail order pcm from Wait4Me. After installing it, I get a P0300 Random Misfire code. I checked all connections, cleared it but it cpmes on again.
The engine light shuts off and doesnt come on with the stock pcm. It did not have any codes before also.
I talked to Jesse at W4M, he says that his pcms are more sensitive to changes and will uncover more problems than a stock pcm. He insists the pcm and the tune is fine but Im bugged because the stock pcm throws no codes and i dont feel any hesitation being also a 5 speed whichd be easier to feel.
