Re: 4l60e torque converter wiring/ ls swap bugs

well today i went and bought a new fuel pressure regulator. that did not really make a difference. it sits at 50 psi while idling. 58-59psi when i unplug it.

i also dropped the tank and tried putting a new hose and clamps between the pump and sending unit. this helped my key ahead psi, while pump is priming its at 58-59psi, when the pump stops priming it holds at 52 now.

truck is still down on power but those things i did today did help. i don't think the transmission is slipping anymore i think this is the engine misfiring/stumbling under load.

truck is now showing code po300 random multiple cylinder misfire.

really would like to see the truck at 55-60psi for fuel pressure... not sure what else to do? if i unplug the regulator and it jumps up to 59 then it couldn't be a clogged filter could it? pump is way quieter now that i replaced that hose on the fuel pump.. must of been leaking a lot
