1999 Chevrolet Cavalier LS 4 Cyl 2.40L

If you have a white cloud of thick smoke coming out the tailpipe, the diagnosis part is done. Forget the codes for now. The head or the head gasket is no good. You are burning coolant. Coolant when leaking into an engine combustion chamber burns pure white. Replace all oxygen sensors with the job because coolant destroys O2 sensors. After getting the head problem solved and assembling with new O2 sensors, drive the car for a day and see what new codes set after erasing all these that you have now.
