99 K2500 Suburban Vortec 454
So recently replace the motor. Been running fine except for a misfire count of 2 at idle on the number 2 cylinder.
New parts on engine install.
- EGR Valve
- Distributor/cap/rotor
- Spark Plugs
- Plug Wires
- Every seal/gasket you can imagine
- Timing Chain/sprockets
- PCV Valve
- Oil Pressure Switch
- Head Gaskets
- Fuel Injectors
- Thermostat
- Radiator
- Oil Pump
I have a code for EGR not recirculating, and Bank 2 Sensor 1 02 sensor. The EGR I attribute to an exhaust leak(need to have a section of exhaust welded back in currently it's flex tube).
It's been running and starting fine, taking a little longer to start sometimes but nothing horrible. Well today it started I moved the truck, shut it off, and tried to start it again. It sputtered and shut off, then did not want to start. I had to give it some throttle to get it over the stumble on start-up. This has happened a few times since, but not every time.
What's everyone's best guess for the cause of the issue? My first thought is idle air control valve. Seeing as giving it throttle helps it. Doesn't seem like it would be a fuel pump issue, but that could also be on the list.
