weird idle and car feels like its on 7 cylinders
my car has a strange idle, it will idle kinda normal and then all of the sudden it will fell like someone revved it just a little bit it does this intermittently. the other problem is the car feels like someone disconnected a sparkplug wire. it runs like a dog under acceleration. i checked all the plugs and wires and they are ok. the optispark is brand new (3 days old) and all the connections in it are fine. could this be the ignition control module?
this is weird because i finished putting my opti in tuesday, got the car running perfect tuesday and wednesday. took it to the track wednesday and ran the best times it has ever run, then at the track, the ground wire that attaches to one of the bolts on the coil broke and fell off. i replaced it with a new ground wire, but ever since that the car has run with the symptoms above

Check out those wires agian. If any of them are burnt even slightly because of those long tubes they wont carry a spark. Try spaying/misting some water over your plugs at night. If you see any sparks when misting the water you found your problem.
