The "Check Engine" light just popped up on my '96 Trooper. I'm approaching 97,000 miles and haven't experienced any noticible problems with the car up to this point. Is a symptom of a large problem or is it just time for a major tune up.

Could be an O2 sensor, and/or possibly major tune-up if you haven't had one in a while, i.e. spark plugs, air filter, fuel filter, etc.

Thanks, and a major tune up is definitely due.
