ck motor mounts.when bad front mount will loosen ground cable,its on the mount
Hey tom its a 1990 pontiact transport van and it starts out fine and as soon as the vehicle warms up it will stall it will start back up but when you put it in gear from park it stall again until cool?
vacuum leak,map sensor
TCC Solenoid.
Look for a vacuum leak.
if you got an automatic depending on what gear it is you may need a 2800 or 3500 rpm stall in your torque converter call a transmission shop if that's it they will help you
It depends on the gearing of the car. If you are in the highest gear and 40mph in that gear is under the idle rpm of that car than you will stall.
i have 94 cadillac sadillac that keep cut off when in gear
I had the same problem with my 1992 grand am after it got warmed up. Once it cooled down it would go just fine. I determined that the torque converter lockup solenoid was bad and would not disengage once the transmission got hot. It will seem like you are dropping the clutch when you put it in gear, because the trans is locked in gear.
Ignition module is bad I had a similar problem on a Pontiac grand am- it was the torque inverter. It would idle fine, run in nuetral, but as soon as it was put into gear it stalled with a thump.
Travelling to slow in a high gear, so clutch in and lower the gear.
your tcc could be faulty, assuming its an auto. faulty neutral switch maybe
Check your transmission fluid level and also if the gear chamber is not well greased then it will make them stick causing the vehicle to stall.
