Help! The "Check Engine Soon" light on my son's 1995 S10 Blazer is on. Any suggestions. Car has 100,000 miles, sounds and is running good. Can't find entry in Chilton's manual. Thanks, Joe

Not enough info. Do you know how many codes or conditions can cause the light to come on?

Have it scanned or at least give some symptoms.

Yip, we need the number that coincides with the engine light.

Without it I don't know what you can expect us to do.
