ets and check engine light on in 98 Chevy cavalier
Did u check your enigine cooling fan?
could be the oxygen sensor. that's what it was on mine.
No, only a problem that effects emissions will set the check engine light.
check engine oil for water and check radiator for oil
If it is easy, your gas cap is not on correctly.
you can take it to auto zone or advance auto parts stores, and they will put the scanner on it for free.
What's wrong with my 2003 Chevy Cavalier if the check engine lights on and a friends computer said "misfire cylinder 4 "? It studders also. thanks Dawn

Take off the + on battery for 10 sec that should clear the code.
You need to check all of the mounts. Get a manual to show you where they are.
