IT STALLS AFTER IT WARMS UP WHILE DRIVING - 1992 Oldsmobile 88

Check the ECM grounds, they are under the passenger side kick panel. When the engine goes to warm status, the Oxygen sensors come on, If there is no ground on the ECM then it starts pulling ground voltage across the sensors and that causes big issues.

Replace the Torque Converter Solenoid in
the transaxle

What you have is like coming to a stop with
a manual shift & not pushing in the clutch & it stalls
the motor

The converter clutch is staying locked & your
trans is connected to the motor

It could be the coil is getting old. They begin to lose function when they warm up.

Hi, car stalling problem often means the engine is not getting enough fuel and/or too much air. A cold engine needs a fairly rich fuel mixture to start, and to idle smoothly while it warms up. Any of the following could cause or contribute to this kind of stalling problem which i would not want to exaggerate until i get a clear picture of how the car stalls.

Does your engine stalls when you stop for a traffic light or when idling, or your engine just stalls unexpectedly while driving?
Answering the question will help me determine the cause of the problem.

it could be an egnition module or somthing basic like fuel presure .. prob the pump .. but lots of things can make it do that .. u need a mechanic to look at it

Could be the distributor or the coil by the sounds of it - coils can be effected by heat and fail

if it feels like your driving a standard transmission ,and "you came to a stop light without pushing clutch in"
that will be the torque convertor lock up,

First you must find the engine oil pressure sensor, remove the sensor and repalce it with a gauge. Run the engine until hot and record the reading if the reading is between12 and 25 PSI replace the sensor, if the pressure continually drops as the engine warms up then you have a major issue, meaning there is serious engine wear and a rebuild is nesassary.

Check for vacuum leaks. Also try cleaning the ISV.


If that doesnt work go to vwvortex.com and post your issue there

You need new timing belt and gears. Buicks gears are made of plastic, and become a big glob. Nothing for the timing belt to grab onto.
