No problem, for some reason I thought you did.
I have replaced both the coil and the plug set with new ones, although I really do not think that is the culprit.
No problem, for some reason I thought you did.Sorry don't have access to a Chevy FSM. Online googling indicates you might have a bad spark plug or a bad coil for the P0355 code.
P0355 OBD-II Trouble Code: Ignition Coil B Primary/Secondary Circuit Malfunction
Trouble code P0355 means the PCM has identified an electrical malfunction in the primary or secondary circuit of ignition coil B.www.yourmechanic.com
Any reason why they would present themselves?Those codes do not exist.
By that I mean the service manual. The ECM is suitable for V8s and thus the needed DTCs for a V8 engine are present.
The engine ran great for about two weeks after having the timing done. He would have redone it no charge if that was the issue.Who did the work and set the timing? Something seems off here...
