Could be the catalytic converter.
Disconnect the battery, wait 10 minutes, and reconnect.
I've had problems with the Intake Manafold and also with the spark plug towers burning out setting off the check engine light. I know there are more but this is just my personal experience with my 1999 cutlass.
It means that you need to get the cars computer scanned to find out what the problem is.
The computer stores the codes until it is reset manually. The check engine light does not have to be on to check the codes.
Which engine 3.1 or 3.4
