Re: Questions about Vacuum, Temp gauge wiring, and Diverter Valve
When I bought the car it did not have a Diverter valve installed someone removed when they installed the headers. Question is can I just reinstall a Diverter valve and block the ports off or just leave it removed? But I am pretty sure it causing the CEL.
