Sounds like the ignition module that sits under the coil packs ... did you ever get any codes out of it when the light was on ?

Testimonial: "No...No codes ever...How can I check the module? Oh...Also...the engine idle goes from 7-800 to 1000 rpm just before it turns off... "

    There was problems with both mass air flow sensors and ignition modules on those cars.. Without being able to retreive codes or looking at the data stream you might want to check around for a donor car to try some parts off of . My first thought is the module because of the heat sync problem. good luck.

1992 Buick Park Ave. Ultra TPS problem

The code indicates the TPS is still bad and the code is usually right, but it could be a wiring issue at the TPS connector or less likely a computer issue.
To test the TPS circuit, you need to check voltage and ground from the ECM - 5v is the normal reading between the ECM reference circuit and the ECM ground circuit at the TPS connector. Checking the TPS signal circuit to the ECM requires monitoring the TPS signal on a scan tool while jumping the 5v reference and the signal circuits. The TPS reading should go from high when the circuit is jumpered to low when the jumper is removed.

94 Buick Pk Ave. restart problems

I had the same problem once, bought a new radiator pressure cap and it ended. Though the Code 41 doesn't play with that theory.

Look at this post for a 1990 Buick, scroll about halfway down the page or search for the word "code 41."
