Installed new Delco Ign module and coil pack today in attempts to resolve my other problem (cutting out after driving awhile). Decided to make a quick run to see if I see anything on the PL. Attached are files for idle/open, idle/close and a quick WOT run....Not the best run as it's on a non-forgiving road, so I had to get off WOT pretty quickly. Also, foot braked too much initial boost and scooted a little on takeoff (hence letting off).
Anyway, to my newbie eyes, the PL is showing me I'm leaning out at just 13 PSI boost. The EGT climbed to 1700, knock started climbing and O2's dipped to low 700's. The WB showed 13/14.
Unfortunately, I don't have a remote fuel pressure gauge, just one on the fuel rail which does read 43psi line off, 38psi line on. Fuel Pump is a Walbro 340.
Am I running out of fuel?
