Car 'stumbles' slightly while cruising and backfires when hot...help diagnose please?
The car used to run perfect before it was down without a battery for a few weeks.
It stumbles slightly when cruising steady at any rpm. Also when the engine got hot (~210*) from idling for a while it would backfire (not loud, a popping sound) if I revved the motor slightly...but it would only backfire when it got hot (above 205*).
I did the idle reset procedure and set the TPS at .96
I'm going to check the timing at lunch (I had it at 10*), and maybe reclock my ProM
Any ideas or suggestions why it's stumbling while cruising???
