I've notice for a few weeks that at idle and up to about 3,000 RPM while in neutral the car has a slight miss in it but it's not constant. I don't seem to feel it while driving under a load but it could still be doing it because it's so slight. It's got new MSD wires and the NGKs are only about 6 months old. It has the original opti with 146K on it so I'm thinking I need a new cap and rotor. Anybody had this problem?? I didn't seem to notice it til I switched to OBD1 but I dont know what that would have to do with it.

Also the track opens tomorrow and I'm praying for no rain so I can get some new times!! woooooooohooooooo

 

I know it sounds easy but I would guess and say that your opti is going. I wonder our MSD's new cap/rotor kit is? Has anybody tried it?

 

OPTI is your foe! I have replaced three and the misfire is the key it seems!
