with me it was the o2 censer
latex from rubber trees is mixed with sulfur during vulcanization process
Low fuel pressure
In my experience with my Chevy it was a ground wire
Black smoke usually means the engine is running too rich. The fuel/air mixture is incorrect. Blue smoke is oil burning.
have you checked your fuses?
The 2005 Cavalier could have a fuel leak. Have the entire fuel system checked, as a fuel leak can cause a dangerous fire.
There are several things that can cause your 1995 Chevy Cavalier transmission not to go into drive or reverse. The most common cause is a lack of transmission fluid. A broken shifting fork will also cause the problem.
bad o-rings or not seated and tightened down properly
Blown Head Gasket or Bad Cylinder Head
A rubber burning smell and smoke near your two front tires could be the result of sticking calipers. The brake line could also be the cause of the burning smell.
The 1997 Cavalier has two motor mounts, as well as a transmission mount. If the mounts are broken the motor can move around and cause damage to components under the hood.
The trans is electronically shifted so the sensor being bad is a likely cause.
You need to check all of the mounts. Get a manual to show you where they are.
A flat tire is one possibility
Have your ball joints checked out.
you most likely need an alignment or your tires just need to be balanced
a bad head gasket or intake manifold gasket.
The fog light bulb on a 2004 Chevy cavalier LS sport should come on when the lights are activated. If it doesn't, first check the fuse for the fog lights, then the bulb, and then the switch. One of these things is likely to be the cause of a light not working.
The vacuum lines for a 2000 Cavalier are located all over the engine bay and under the dash. A break in any line can cause rough running.
the first thing to check is the manifold air temperature sensor
A loose gas cap will cause this. Check that first then have a local parts store such as Advance clear the code for you.
i was wondering whether the switch at the parking brake could affect this problem.
TRY CHECKING TO SEE IF YOU HAVE A HIGH BEAM HEADLIGHT OUT. tHIS WILL CAUSE THE PROBLEM YOU HAVE.
