My vehicle first had issues with not starting unless i primed the intake plenum with fuel. It would run fine after that and start fine while it was warm. If it sat for more than an hour or two it would not start without being primed. Before I could change the fuel filter or pump, combined with the starting issue, it began losing power and would not rev past 2000 rpm and produced a loud squealing noise (not a belt). I ran some codes and got, fuel too lean, and a random misfire code. I have changed the fuel filter and fuel pump. I am getting around 60 psi when i test the fuel pressure, good. Now i get the random misfire code but the plugs all appear to be fine. Is my only option to remove the CSEFI unit and start to replace the fuel meter body. What else could be causing the random misfire.
