Same EFI problem
Ok guys, here goes again.
As long as I'm on the interestate and going 65mph no problems.
But let me run around town and have to push the truck to pull it'll start bucking.
New; FORD Parts;
front and rear pumps FORD OEM's complete assy's.
fuel switching canister, fuel filter
tank selector switch
both eec and fuel pump relays
tps
New tuneup parts, etc.
Can this truck run w/o the hi-pressure pump along the frame.
When I pulled the 5th wheel camper last it started this mess and smelled almost like it was leaning out. No cat on exhaust, so its not stopped up/clogged. It got so bad pulling the mountain that I had to stop and lock in 4lo to pull the last bit.
This is driving me crazy. Seems the hotter it gets (both ambient and eng. temps) it get's worse. I can back off on the throttle and it'll even out, but as soon as I'm back in it, it'll start back.
This one is kickin' my butt.

OK, this may sound stupid, but next time it does this, take off your gas cap and see if it doesn't clear up....like fast. It sounds to me like maybe you have a fuel tank vent problem.

My FS Bronco tank conversion for the rear tank is working great too.

check your engine coolant temp sensor. not the one for the guage, but for the computer. if it is fine i would have the ignition module tested. if it is good then i would replace the coil. i would assume that you already replace the plugs, wires, cap and rotor.
