oil looks fine, less than 2 k on the oil, and I haar nothign from the lower end of the engine (knock on lots of wood the way things are going) I generally drive the car 500-1000 miles a week, as I have a long commute to work.

ok, all three primary coils seem to read at 1.5 ohms (underside of the coil pack)
and the secondary (top posts) seem to read at 11.5k ohms. Does this pack seem bad? This the the pack I removed from the car yesterday.

My FSM doesn't specifiy primary (underneath) resistance, but normal secondary (top) should be between 11k and 13k. So that seems good.

Injector resistance 14.5 ohms? Does idle change if you tap on the MAF? Any codes (paper clip trick)?

I have an otc 2000 scantool that I used to use on my monte, however I only have a chip for it to 1989. Anyone on long island have a pathfinder 92 chip I can use to put my scantool on her?

I havent played with the maf at all since I figured there would be no way for the seafoam to have made it up the intake and into the maf, but I will mess with it. I have had other cars with maf issues and the symptoms were different.

Any ideas on what could possibly have been damaged by the seafoam?

Unplug the MAF while its idling, and let us know what it does. If it got damaged, it'll cause hell.
