1992 Buick Regal Custom keeps dying in gear unless I double pedal


unfortunatly it sounds like you are having issues with the torque converter. it sounds like it is locking up all the time now. this requires the transmission to be taken out to change it i do not know what your experience is so not sure if you have the tools or knowledge to do it yourself.

1991 buick regal starting and running problem


Sounds like your car is overheating. If you have a temp gauge it should show that. If you just have an idiot light, by the time it comes on it's already too hot to operate. AFTER the car is cooled down, open the radiator cap to see how much coolant has been lost. Chances are there is alot missing. Add WATER (no sense in adding coolant if it's going to leak out) and idle the car at home. Look underneath as it warms up to find where the leak is.
