I had a running rich problem while fouling plugs (1,4,6, & 7) with the advice of thirdgen member who says it sounds like a leaking injector so I traced it down to the passenger side injector. I installed a brand new one from Turbocity then I change the plugs and wires before giving it a test drive. It started pinging and overheating so I made it back home I noticed my fuel pressure drop from 11psi to 6psi then increased the pressure to 10psi and it wouldn't increase any further than that. My idle speed has increased and the timing is just below the 0 mark on the timing tab.
