Fueling Issue? Or injector?
Fueling Issue? Or injector? Well my car started acting weird a while back and I thought nothing of it. Got tired of it and started to dig into it. I am unable to just flat rev it up from an idle. When I do it just acts like its starving for fuel (wideband goes totally lean). Looking at the fuel pressure it doesn't drop off significantly like it would be a bad pump. I swapped to the other pump and it does the same thing. I have lonnies dual 340 setup with FIC 2000 injectors w/ adapters. I use to be able to tbrake it by mashing it up to 4500. Could the adapters be the issue with this? Not allowing full power to get to them? I've heard of issues with these and people don't like using them. Also changed plugs, swapped coils, and wires, still nothing. Base pressure is set at about 53.

If you know someone that has EFI live or HPtuners I would have them look at your injector data. You have good fuel pressure and good spark then I would look at the data. My passenger side some years ago just started dumping fuel and fouling plugs. No reason why but my PCM went corrupt.
