I've got what appears to be an ignition breakup problem, and if the new plugs I picked up today don't fix it, I need to start changing out ignition parts to find the bad one.

Anyone in central PA have some known-good parts I can borrow?

(And if you're not in central PA, but feel really helpful, I'll pay shipping both ways to borrow them for a week or two!)

I have a good FD primary coil you can have if you need it. Also a good low-mile set of plug wires.

 

Check the resistance on your coil packs. Thats the easiest way to find out of their good or not. Check it with an ohm meter.

 

The coil pack windings and the spark plug wire resistances come out just fine. The plugs are new. People say that some problems don't show by these tests, and that I need a good swap to find the problem.

I'm still getting bucking between 2-8psi under load. I get sometimes get it to breakup by revving in neutral, too. This is all ignition breakup, I assume. I have a new set of injectors coming tomorrow, but I'm not sure they would cause bucking. Dave, if the injectors don't help, I'll probably send you a PM regarding shipping the parts to me for a while. (If they fix it, I'll buy them if you want to sell them)

In any case, I'll take this back to the 3rd gen section.
