It would be interesting to know which code is present when the check engine light is on. The next time the light comes on, take your car to autozone or advance auto and have them to scan the computer. Write down the codes and post them here. The codes will give me a good place to start diagnosing the problem.
Meanwhile, check for obvious problems such as, make sure that the temperature sensor is plugged in (it's screwed into the intake manifold near the throttle body and should have a two wire connector plugged into it), vacuum leaks, disconnected wires etc.
Don't forget to post the codes from your car's computer.
