My 2003 Monte Carlo SS suddenly started running rough and hesitates when accelorating,and will die when sitting at idle speed. It only does it when the car has been running for awhile.
The ck engine light should not be ignored, what sensor was shown to be bad ? Have it scanned again and replace the sensor that is bad if it still runs rough you might want to consider a tune up. Plugs, wires, fuel and air filter's and clean the throttle body with some gumout. It could also be the IAC motor Idle Air Control. Good Luck

My check engine light has been on for about 2 years. I had that checked and it was determined to be a sensor and no big deal. So, I was thinking last night how I wish I had had that fixed so I knew if the check engine light would have come on for this problem.
have it checked a gain other codes will be in there
is your check engine light on?
