1997 Chevrolet Cavalier - Answered Questions & Fixed issues
1997 Chevy Cavalier. How do I bypass the anti-theft system forever?
Question edited for clarity and correct name of vehicle.
You can't bypass it Cherie, it involves transponder chips, receivers and the engine computer (ECM).. The anti-theft system is there to stop theft of the vehicle, basically what you are trying to do. You have to fix the system, not find a way around it. This is the reset. As long as you battery is good and fully charged, it should only need doing once.
Just leave the key in the run position and the "Theft System " light on the dash will be flashing. Leave the key on for about 10 minutes and the light will stop flashing and go on solid. Then the theft system is disable

Misfire, idles high
I would start with ect. That is the engine coolant temperature (sensor). That sensor monitors the coolant temp and tells the computer to increase engine RPM so the engine warms up faster. In the mornings when you first start your car and it idols high, that sensor is sending that information. If you have a code for this sensor start there.

Could be a fuel fault, with a pressure gauge check the fuel pressure and flow , if the pressure is low check the fuel pump and fuel regulator , if the flow is low replace the fuel filter.
