Air Pump Control Valve

[ofset]

Hey RAS thanks for replying. checked it this morning and its definitely leaking from the front of the pump only. (maybe the rivets in the back are fine) so ill probably just replace all of them just to be safe.

I was getting misfire codes and took it to the mechanic to change the PCV/CCV valve. Now i am thinking that the misfire codes are from the SAP

I also just replaced the line from the SAP to the Shut off Valve that is connected to the front of the engine.

I also unplugged the hose that goes to the shut off Valve to see if it kicks air out instead of sucking in. seem like its not pushing air out so the shut off valve should be in good shape.
