Re: 1996 cavilier runs great until it warms up
Does the coolant gauge on the dash work properly,is it running cold or hot?Any check engine lights? They are very popular for coolant temperature sensors that go bad.Its hard to say from here ,Ive replaced enough of them on those cars with that problem.Make sure you have the proper amount of anti freeze first
It may be the ignition module. You will need to check to see if you have spark to the plugs when
it stalls. If not the module may be the problem. You will need to remove the module and take it to
a auto parts store that has a tester that can check it.

You need to find oput what you loose when the truck shuts off, all you need is Air, Fuel , and spark to run one of the three are droppuig out when it stalls and will not run. Chech the carb for gas it sounds like you have a weak fuel pump.
Hi, It sounds like you have a bad temperature sensor. Which is a plug like sensor that screws in. You will find it on or near where you coolant hoses connect to your engine. usually near the upper hose. Which would be screwed into the neck that connects to the head or on the head itself. Also check your radiator it could be plugged into the back (facing the fan). also if you have not changed your thermostat it wouldn't be a bad idea to do that also. which you will find under the neck of where the hose connects to your engine. Usually 2 or three bolts. Make sure your engine is cooled down when doing this service to your engine because of built up pressure in the coolant system which will cause burns or worse. I hope this helped you out. It would be greatly appreciated if you could rate my answer, thanks MIKE-
Your ECT (Engine Coolant Temp) sensor is bad. What's happening is at cold start it richens up the fuel mixture and as it warms up the ECM thinks it's still cold and essentially the "choke" is still on. Also check your coolant level. If you don't have enough coolant in you engine/radiator, the ECT doesn't know what to do so it thinks it's cold.
