Default Re: 1991 Zr-1 Stumbling off idle

Dynomite - I checked all plugs before digging further. They appeared normal, but may replace them anyway. Wires have been replaced at some point. They are the red wires made by Packard. Vacuum seems to be holding fine, pump comes on at start up and stays of.

David - hope to eventually get to headers, ported plenum, Haibeck chip, and maybe a set of 4:10's. It has a B&B exhaust on it already. I've ordered a few things from Jerry already.
