My 92 bonneville sse is stalling while I'm driving. There is no puterring or anything like that. You'll be drivin and the service engine soon light comes on and then it stalls. I have already replaced the fuel filter, pump, and strtainer. I dont know what else to to please let me know if you have a suggestion.

Please disconnect and clean all connections on both the positive and negative battery cables, both ends of each cable, including at the alternator, starter, and all ground locations in the engine bay. Reassemble each connection after cleaning the cable ends and the mating surfaces (mounting posts) with dielectric grease.

This is a common problem for your generation due to age, and your symptoms are a classic example of this.

I checked a bunch of the wires they werent dirty. are their any other things that could be wrong. It has lots of electronics in it to

its sounds like your alternator is crapping out or the wiring, not the terminals, are corroded or damaged. Do a volatge drop test to test the wiring and and a Ac voltage check to test for AC ripple to test the alternator diodes.

Most members here won't have a clue as to what you are saying in this statement.

He is having a stalling issue, not saying anything about dim headlights etc. If you suspect an alternator, please ask the questions that would point toward low voltage.

Also.. a suggestion. I see in your sig that you have more training on these systems than most. Try and phrase your tests/suggestions in a way that the average person can understand and try to check.

yes it is true I dont know alot about the car. I did get a computer diagnosis on the car on of the thins was a spark refrence circuit could that be the cause or just something else.

Please read Techinfo for the procedure for pulling codes, and report the number back to us here.

i took it up to autozone and they did it for free. They got 58 and 17. 58 was some anti theft thing and they didn't have 17 so i looked it up in a book I got about the car. #17 was a spark refrence circuit. Now I have to wait ti l it stalls so I can test it then.

Sounds like this might be another case of the crankshaft postion sensor cutting out when hot. Might be something to look into.

Spark reference circuit could be either the cam or crank sensors, or the ICM.

Ignore 58. It'* a known bug in the 92 PCM.
