1992 Buick Lesabre keeps stalling

[Kalispellbob]

I dont know if anybody can help but my 1992 Buick 3.8 stalls after it gets up to running temp. I changed crankshaft sensor and camshaft sensor if anybody knows what is going on i would appreciate some help Thanx Bob

Do you have any error codes to share with us?

[Kalispellbob]

sorry not yet i thought about bringing it over to mechanic to have him put scanner on it

[Kalispellbob]

Put scanner on it and no trouble codes showing what to do now..

It could be many things. It could be a bad ECM, or bad wiring, or your Pass Key system could be malfunctioning, or some engine sensor is malfunctioning at engine temperature (oxygen sensor, MAP sensor, engine temp sensor, intake air temp sensor, etc. etc.), or your camshaft magnet might be broken (which is what your cam shaft sensor is sensing), or your distributor coil could be bad, or your spark plug wires could be faulty (unlikely), or you might have gremlins living under your hood.

However, most of the above would set a code.

It sounds like a trip to a mechanic is in order.

I dont know whats going on but now it is bucking after you drive it for awhile, when it starts to buck check engine light goes crazy, speedometer goes crazy up to 100 down to 20 back up again then it will stop and run good you tell me i dont no

If the check engine light went crazy after the last "bucking" event, you should have a code. Have you checked the battery terminals and alternator output?
Have you considered entering her in rodeo competition?

Sounds like an electrical issue. When you shut down does your speedometer naturally fall to the right? So, if the car is intermittently shutting down it would look like it was spiking up over 100mph before coming back on and down to your actual speed.

Mine did something similar to this and it was a shorting ignition switch.

I hope you have fixed this by now.

My car did the same thing and it was the alternator battery combo.

New alt and battery water top-up fixed it.

When your power goes too low everything starts to shut down and
your car quits.
