Good to know. But you need to test them hot as well. Get the engine hot and when it stalls, check them. Also check the primaries and secondarily.

tested after stalled and still under 13. ended up going to advanced and took a ohms reading on a new coil pack and it read 12.77. So I now know mine are ok and in range! I think I'm going to just push it in the river! Could the ICM be causing this and if so whats the best way to test?

When it stalls, pull a plug wire and put a old plug on the wire, lay it on ground and crank the car. Do you have spark?

I do have spark right after stall. I have noticed the last few times though my starter was having a hard time cranking. Could a bad starter that would draw power cause a stall? Other than that I have to bring the wife to work tomorrow in Eau claire so I am going to see if any auto parts store has an OBD 1 reader that i can use because this hunting crap is getting old!

A failed MAP (Manifold Absolute Pressure) sensor can cause a lot of problems. That may the culprit, although I would not overlook the cam sensor.

A MAP sensor for mine cost $40 at the local Advance; if the Series 1 is close enough to the Series 2, you can change yours in five minutes. A cam sensor… well, you'll have to wait for someone else to chime in on that one.

just reset codes and the only one that came up when stalled out was cam sensor. Plus i don't believe on the 92 there is a MAP sensor? so I guess i am going to pull the wiring and inspect it and replace sensor. will keep updated!
