Hi there. After reading your question, it appears that the problem you’re experiencing is either caused by a problem with your fuel injection system or an electrical fault, especially since your car is 22 years old and has 134,000 miles. Sometimes the problem that you’re describing is caused by the mass air flow sensor.

The MAF sensor is engineered to work with your vehicles ECU (engine control unit) to measure and regulate the amount of air that flows into the fuel injector and throttle valve. When it works correctly, it provides the right air-to-fuel mixture to ensure your car runs smooth. When it malfunctions, it can cause your engine to run erratically, causing the RPM to spike then shut the vehicle off. However, there are multiple mechanical and electrical components on your Buick that might be causing this issue.

The best solution is to contact a certified mechanic that can visit you at your car’s location - especially since the car is having difficulty running smooth. They’ll look over your car, take it on a drive test (if possible), and diagnose the stalling issue. From there, they can perform any repairs so that you can get back on the road safely.
