82 Corvette Diverter valves Rough idle and engine dying out

My 82 starts with no problem. But would not idle and then dies out.  Years ago I change the diverter valve (used unit) ran fine without problems.  Now it started again.  Wondering if anyone know where I can get new diverter valves or how to repair them.

Any advice is appreciated.  Can drive car, would just run rough and dies out.

Thanks for any help.

A diverter valve shouldn't have any effect on how the engine runs. The EGR valve, however will. Since it is an '82, I would suggest scanning the ECM for any trouble codes that might be stored, and troubleshoot from there.

Thanks for the reply.  Check for engine code.  Got code 22, TPS.  So I will be ordering 1.  

Thanks for the help.
