Had same problem and changed the ignitionmodule, problem solved and runs great
There could be a problem with the power of common ground to the Cavalier light and sun roof. Check the fuses and wiring for the problem.
Bring to a shop that has an ABS scanner to determine the problem
I had the same problem with a 1992 Park Avenue with the 3800 engine. I first replaced the electronic ignition but that did not fix the problem. I then replaced the crankshaft heat sensor. That fixed my problem.
MAYBE IT COULD BE A BAD SENSOR. IF IT IS RUNNING GOOD I WOULD JUST IGNORE IT.
There could be an internal problem with the transmission. Check the transmission fluid for a burnt smell or odd color, indicating transmission damage.
The abs light being on for a 2000 Cavalier indicates a brake problem. The brakes could lock up when the pedal is pushes hard, or pulse.
I had this problem and took my 1990 cavalier to a shop. Nothing came up on diagnostic so they decided my ignition module and coil packs needed to be replaced. This fixed my problem but costed me around 450.00!
Check the ignition module. They can fail when hot
I dunno what the problem is but I have it and can't figure it out...I'm thinking I might have a damaged ligament or something might be wrong with my ovary....
check oil and oil pressure if good sell it
Could be a linkage problem..
the problem could be in the fuel pump itself or there could be a loose wire connection where the fuel pump plugs in.
