Check Engine Light Due to Restricted Secondary Air Injection Check Valve on Chevrolet Corvette

One or both secondary air injection check valves may become restricted causing poor air flow resulting in illumination of the Check Engine Light. It is often recommend to replace both check valves even if a fault code is set for only one bank of cylinders. Replacing only one valve may result in a return trip to the repair shop.

First I was told it was a due to bad "smog" pump (AIR pump). That was fixed, but the check engine light came back on. I took it back and now it resulted in a bad pcv valve. replacing both these parts took care of the problem. But it your case it might be only one of these issues.
