>the only things I can think of is possibly a spark plug crapped out and is
getting intermintent firing--what plugs are you using, and what is the gap.
If you have an aftermarket coil, most plugs have to be gapped differently.
Check the little screw on caps on the plugs and see if any got loose--these
little critters will make your engine run rough because they can't get the
proper contact. If plugs,coil, throttle position selenoid sensor check out
good--about the only thing left is a bad spark pickup relay in the
distributor, and those little gems are around $200 smackers. ALso make sure
that your distributor cap isn't cracked--use a flashlight and from inside
the cap make the light try to shine (hope not ) through the plastic
housing--cracked caps scatter the spark instead of concentrating the energy
to a specific post.
