I'd check the coolant level first, then the thermostat.
There is no ETF light on a 1996 Chevy Cavalier. But there is an ETS light which stands for 'electronic traction system'. This light turns on where there is a problem with the brake system.
Check the coolant levels. Insure that the cooling fan turns on when its supposed to, and the thermostat is not stuck closed. Make sure that the water pump is operating correctly.
not likely PCM problem... most common cause is either ... Bad Cooling Fan Relay Blown Cooling Fan Fuse or Bad Cooling Fan Motor
spark plugs
it has a bad connection with aground or you have problem with swith or your outlet foryour bubb is bad good luck
check if it is getting fire
There are none, timing is adjusted by the ECM by advancing or retarding the spark in each cylinder. There is a chain in the side of the cylinder head that turns the cam but this is not adjustable.
Check for fuel Check for spark
Sounds like your dimmer switch isn't working or it is turned all the way down for night driving.. It has a setting that allows you to turn off the lights on your dash and radio for driving at night. Locate your dimmer switch and see if it is turned down all the way. If not it may have gone bad and needs to be replaced.
My 1986 Honda Accord Dx just started idling rough and dieing at turns and stops it is a carburated 2.0 witha maunal transmission
The small block chevy turns in a clockwise rotation.
There is a sensor on most modern cars which turns on the fan when the coolant temperature reaches a certain value. If this sensor is bad, the fan may run continously.
