Car out of winter storage, now shaky idle, stumbling off idle
I just replaced the plugs myself, with Super Copper Bosch, no problem on initial start up, no problem once moving, what should I check for?
Do you think it might be carbon build up on the pistons?
The spark plug connectors had light oxidation/rust on them but seemed fine. Should I replace?
Thank you very much for any suggestions offered.
