I have a 1994 Buick Regal Custom with 74,000 miles on it. (Incidentally, I DO NOT reccomend this model as it has been nothing but trouble.) The latest issue has me stumped. The car performs well enough on the highway, but when I drive at speeds below 45 mph, it stalls at random intervals. Any ideas on why it does this and how to fix it?

What to check next

Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.

Arrange testing during an actual stall and record the relevant fuel, ignition and engine-control findings before selecting parts.

Mine was doing something like this and it turned out to be a faulty Crankshaft Position Sensor

I forgot to submit the cause of the problem. It turned out to be a Crankshaft Position Sensor.

It was in bad shape and was cracked. The car has run good ever since.
