Tune up
Bad ECM or bad distributor
The engine coolant sensor could be at fault.
transmissions works fine when cold but when it warms up it spins or acts like it is in neutral I have to turn off engine and let it cool off Help.
Checl your manual for a cold start injector. if it has one check your voltage after it warms up. if you have voltage after car warms up you have a problem with the circuit. if you don't have voltage, remove and plug the fuel line to this solinoid, start and run car and check your symptoms again.
it could possibly be a bad coil, crank shaft sensor, or cam shaft sensor.
Probably your transmission fluid level is low. You should check it, the add some.
Check the coolant temp sensor. The one for the computer not the guage if so equipped
check the egr vavle or the purge valve
Coolant temp sensor
it may be an exhaust manifold gasket. when they are bad, they make a tapping soud til it heats up and semi-seals itself. it's one thing to have checked.
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?
fuel injector or crank sensor is at fault here
