1996 Chevrolet Cavalier

Radiator cooling fans not working? The ECM is protecting the engine by shutting it down.

yes that sounds like a bad coil it will be okay when it's cold and as it heats up it will malfunction

It could be a head gasket. To test, have or do a chemical test for exhaust gases in the coolant. It's an easy test, and I have heard that autozone will rent you the tester. All you have to do is buy the test fluid, hook the tester to the radiator cap opening, car running at normal temp., and watch the test fluid container to see if it changes color, verifying exhaust gas in your coolant.
You could also have a shop do a leak-down test and check for a head gasket failure that way.

What engine?

Tps maybe...any codes?

The problem is the torque converter solenoid. I had it happen on my 94 Cavalier a few years back and was a cheap fix at the local car mechanic. What happens is the transmission warms up and hits a certain speed where the solenoid engages, but then it sticks and won't disengage until it cools down sufficiently. When it sticks, it causes the car to shake when slowing down and will snub out the engine if you come to a stop.

crank sensor

Possibly the thermostat was installed backwards???

it is most likely **** in your gas tank  the **** gets stuck in the fuel pump and then it wont send fuel let me know what you  think

Check all of your connections at the coil pack. Ensure that the coil packs do not have any corrosion under them were they connect into the base module or any of the connections, even plug wires. I had this same problem with my 2.2 in a 99' s-10. Pulled the coil apart, cleaned it up and and put di-electric grease on it, all better.
