Okay, the primaries are all reading 1.1, which is out of range.
Also, the secondaries were all reading between 7.8-8.1, also out of range.

When I took the ICM to AutoZone it said the "Setpoint" was what failed, that'* all I know. Before I make any financial decisions, I'm going to go ahead and change the spark plugs and wires, then see what happens.

well, did good a couple times around the block, thn on my final pass it started hesitating a little. I parked it and revved it to about 3000-3500 RPMs, and as it was dropping back down I got the pop again. so it looks like I may be investing in an ICM and Coil Pack after all...

reving in park is doing nothing good for your engine... i wouldnt be suprised if my exhaust was popping either under those conditions..

Well, I discovered that the ICM was under warranty at AutoZone, so that was free exchange, and I dropped $50 for a new coil pack, and...

GUESS WHO DADDY FIXED!...

lol, since this WAS the problem... has anyone heard anything about some recall GM did on ignition switches in Bonnes? I didn't see any for my specific model/year, but I seem to have 2 out of 3 of the listed recalls there were, so hey, why not expect it. lol

I want to say thank you to everyone who helped! I sincerely appreciate it.

Now upgrade to the Delco type ignition with three seperate coils, and ditch the magnavox setup forever.

I was actually going to ask about that... is the Delco setup better? I would assume it is seeing as it seems every year after 92-93 uses that configuration. What actually makes it better, do you know? I'm seriously considering doing this, but I need to know if there'* any changes involved other than just switching it out. I'll look to see if there is anything in techinfo, I didn't notice anything though...

[EDIT: Found it, thanks! lol]
