Question about 1993 Buick Regal
My 1993 Buick Regal 3.8 V6 dies while I am braking. It only happens when the engine is warm and the engine is under light or no load and (what makes me really confused) if I put the car in neutral it starts right up. Any idea what might cause this?
Check to see if you have a lot of dirt in the throttle body. Clean the throttle blades out with brake cleaner or throttle body cleaner. You'll see alot of dirt come out. Keep spraying until it comes out fairly clear and wipe the throttle body out with a rag. If this doesn't do it, you may have a problem with the throttle position sensor (TPS). This sensor controls the idle after the car warms up and keeps it from dying when you brake or sit at idle.

If this car sat for a year you need to change the fuil filter you might need to change the o2 sensor..
