So I drive a 1999 chevy Cavalier and ive been having many problems with it. It blows black smoke sometimes from the exhust, on the hot and cold gauage the needle works its way to the hot end all the time,...


Hi,
It sounds like you have alot of problems which may only be a couple.
Have the coolant thermistor checked, it sounds like this is not switching off and causing the engine to over fuel, making it run rough and blow black smoke out the exhaust.
Have the engine thermostat checked it maybe faulty causing the engine to over heat., have these done and see how you cars goes then.

  1. Im assuming you have a quad 4 engine.. so remove the cover w 4 bolts and inspect the plastic where the 4 plug boots go for cracks , this was a common problem with these engines, if none are found replace the ignition coil thats defective ..Not likely to be a coil..but you never know I'm more inclined to say hairline cracks in the coil retainer .. ps if the catalytic converter got as hot as you say,, its likely toasted and will fail an emissions test like we have in ontario canada ..good luck,,eh lol

Backfiring, rough idel


I would check the exhaust pipe a little closewr. White smoke can also mean a blown head gasket. Check the tail pipe to see if moisture is present. Also check coolant level. A blown head gasket can also cause related problems.
