good luck... hope its nothing serious. If it turns out to be anything with the EGR valve, call an Acura dealer to see if your car is covered under the factory recall. You just give them your VIN number, and they will be able to tell you if your car qualifies. A lot of 97 3.0's had trouble with the EGR valve... My CL had it cleaned once, and is now due to have it replaced.

This is a common source for a CEL on the CL... and Acura covered most of them on cars up to 100,000 miles.
