A previous owner had the (leaking) water pump replaced and at same time replaced the opti-spark. Stil had a reading CPS. I have since had the CPS replaced and the ECM replaced (technician Chevy dealer). I still have the service engine soon light on and code is for CPS. The car runs great. Any suggestions to make this warning light go away.

LT 1 drove the car 150 miles on Sunday with no issues, with the exception the light is still on
