No, she took it to the dealership to have them do diagnostics on the car. I have spent two weeks chasing my tail with this rediculous problem and driving her to work. Something'* got to give as my life is on hold until this pile is fixed.

If the dealership comes up with nothing (which I suspect), the cables will get cleaned next. The main power line from B+ runs to the starter only, or does is go elsewhere too?

Not positive as I haven't had issues. There are two cables coming off the battery for power. Then the ground also can cause problem. There are many points of contact and plenty of areas to have issues.

I also noticed the driver rear and under the driver seat are wet(obvious leak). I checked the ground blocks in both side kick panels and they look perfect, so those are not the issue. Is there something under the seat I need to worry about?

The basics is Randman1 bought the car with stalling issues. He pulled the interior out, let everything dry. Fixed all the water leaks and it has never stalled again since.

Default Possible Fix!

I may have found the problem... after I replaced the o2 sensor and cleaned/greased all the power and grounds, I was testing the o2 voltage at the computer harness. I shoved the ground probe in between the PROM access cover and the case of the ECU. When I did that, the "ding, ding, ding" would happen everytime I would push down on the PROM cover...

I unhooked the battery, pulled the PROM, reinstalled it and drove the car for almost an hour with no sign of the "ding, ding, ding" or stalling. It seems the PROM was loose for some weird reason. Tomorrow will be the real test, as the car will get driven much more.

Crossing my fingers.

With the ECM lying on the floor plugged in and the PROM cover off, if you push against the PROM one direction, the idle speeds to 1.5k, if you push it the other way it almost dies. I put dielectric grease on the pins for the PROM, but it still is crap. I guess hitting up the boneyard for a different ECM is my next move eh?

Uh yeah, get a new PCM, from a 92 if you can, of not, just put your PROM into what you get. If you go to ACDelco.com, do a search for the control module for your car, copy the part number, then you can cross reference it to what other vehicles use that module with different PROMs. It was used A LOT.
