I fought an idle to 3kish misfire all summer. Turned out to be my opti. I put one of the MSD billet jobs in there and no more issues. Something to keep in the back of your mind. I have found these are fun cars to drive and there are some really fast ones out there. Have fun with it and if you need help, let me know.
Thanks Jon, I just discovered what I think will make a huge difference. One of the 3/8'' vacuum lines was off of one of the PCV valves. It has a newer MSD Opti Sparks on it. I got a spare too. Optispark doesn't seem to be one of GM's better ideas.
