i checked fuel pressure today, at an idle it sits at about 30 or so, but if i give it any gas, it jumps up(didnt see it hit 40psi though, which is what i thought they were supposed to sit at).
when i just turn the key on without starting the truck, it jumps up almost to 35, then slowly drops, but fast eanough you can watch it dop down.

what could this be? could it be the source of some of my problems?

i ran the motor, and reved it a little and POP from the intake, like a manifold backfire from a carburated engine. i pulled various spark plug wires while it was running and noticed little to no change in the way it ran, which has me really stumped.

does this sound like my timing?
