The first 10-15 mins. it runs great, but then it will stall, jerk, and die when I brake or stop completely. To keep it running I have to slip it into neutral while stopped, and slip it back into drive when I need to take off. It jerks a little when I take off too. The spark plugs and wires are fine, and the coil pack was replaced, so I don't know if the timing is off or what. Please help I need to fix it ASAP!
My 92 Buick Century 3.3l has been jerking and dying when brakes are applied?? on 1992 Buick Century
It sounds like a torque convertor clutch switch problem. It keeps the torque convertor locked up and feels like it is stays in high gear and not shifting down.

Very easy fix, Unplug the transmission lockup solenoid which is under the hood & easy to get to. It fixed my 92 Buick Century & now it runs great
