Dan, I installed an overhauled AFM as part of this troubleshooting process, because the Air Temp Sensor reading seemed off. No change. And even if I was to try adjusting it, what would I adjust it to?
David, I'm glad that the 36 psi with the Key ON is ok.
I would think that a vacuum leak would make the engine run Lean, not rich.
I'm having a little trouble understanding the other two comments you made.
Could my fuel pressure regulator be the source of my low fuel pressure?
