Hello, my father and I have been having a real problem with my 96 LE V6. It has 190k on it and there has been a problem when the car warms up.

The car runs absolutly perfect when it is cold. But once it warms up, it seems like something gets too hot or a sensor is bad so it restricts the motor to only rev up to 2,500 rpm. We have checked all sensors and believe all the grounds are correct. Could this have something to do with the coil packs? Or any other ideas?

Because it governs at this low rpm, the car only goes up to about 60 miles per hour. Its really weird because other than the governing/cutting out, the car runs perfect!

We are so confused and really need help!

 

Have you checked for trouble codes?

How does the engine idle when warm?

Sometimes the coolant temp sensor for the computer fails causing strange problems.

How are plugs and plug wires?
