probly bad gauge or loose wire buy a manual gauge one with the oil line right to the gauge nothing is wrong. the guage is supposed to be high when driving. it will drop when you stop or are idling.
because you broke it!!
A 1998 Chevy Cavalier is an interference engine meaning any timing failure will result in catastrophic damage. A free-running engine will simply stop running until and can readily be fixed.
If the security light on dash is on then it's a passlock problem. If not check the fuel pump first
It can be a leaking injector that floods the engine when it isn't running. GoodluckJoe They asked about a problem that occurs AFTER it's been running a while...not after it's been sitting, with a pressurized Fuel line.
Did u check your enigine cooling fan?
Well yes and no. Both have a 2.2 four cylinder if I'm not mistaken, but I don't think the earlier Cavalier's have the EcoTec motor. And you should be able to get the engine from the '03 into the '97 with no problem.
The check engine light cannot be retrieved on a 1990 Cavalier unless a problem develops with the engine. The engine can be checked for errors, though, by using a tester that is plugged into the vehicle's computer.
blown engine, out of gas janitorial duties.
look at your belt with the engine running (keep your fingers out) the pully on a little arm that bounces is your tensioner.
A problem with the emission system. Need to have trouble codes checked.
Have vehicle scanned to determine the problem
After the engine has cooled to a certain temp, it should shut off. If it is running constantly, this is an indication the engine is overheating.
