Having problems with your 1997 Chevrolet Cavalier ?
Code P0300 misfired detected. I have cylinder 1 and 4 that doesn't spark. I'have changed one of the coil pack and still no sparks. I have voltage tested on the coil wire (brown) and it shows around 13 or 14 volts. I've changed the plugs and check plugs wire. Next step seems to be the CMI...or any other suggestion ? How do I check the Control Module Ignition?
Sound like bad ignition module.make sure where coil pack set in module contacts is clean and making good contact.also make sure plugs and wires is good.
