eratic engine miss

Have you done the timing on the car? What did the plugs look like when you pulled them?

I am with the good doctor on this one. V6 Fiero's for better or worse seem to have that random miss every so often, so once every 10-15 seconds.   

We were able to virtually eliminate it on FieroChicks V6 car by completely replacing here ignition system. New MSD Coil, new MSD Wire, New MSD Cap and Rotor, MSD 6a ignition box, and rebuilt the distributor shaft. That means pulling the shaft out of the car, taking it apart, shimming out any slop, then cleaning all the contacts, then installing a NEW DELCO pickup coil and new Delco Module.   Now it fires and starts even before it feels like it has made one rotation and idles smooth as silk.   

I am kinda on the fence about the new design dist shaft. I have one here and have looked it at it. However I don't really like the setup. Don't really know why, but something about it, just bothers me. John just so we are talking about the same thing here, you mean the 2nd gen 2.8 shaft with the Triangle shaped reluctor vs the old style with the fingers that pass each other, correct. I may take the 2nd gen one and clean it up and try it on my 88GT for Lisa and I's road trip next month and report back.
