It'* funny 'cause I'm having the same idle problem. The last time it happened was the worst. Before, I'd turn the engine off and start it again, and it would idle fine. But yesterday it did it constantly. Every couple seconds it shook and I could also feel it through the pedals. This is worrying the hell out of me. I will be changing my plugs and installing my Taylor wires tomorrow. This will be a start.
If this is a fuel injector problem too, how would I go about fixing that since they're expensive as hell. Can they be cleaned and reinstalled, and if so, how?? Thanks a lot.
