[QUOTE="Ljsasken, post: 436053, member: 20057"] Hey all. So my jeep has been spitting and sputtering around 25-2800rpm in 5th when easing into it. Or anytime you don't ease into the throttle in 3rd, 4th, or 5th. It's been nuttered, TFI ignition swap, NOS original motorcraft 2150, no vacuum lines except brake booster and vacuum advance, cold air intake, return fuel line has been plugged to run a clear fuel filter I've heard a pinhole in the fuel line could cause something like this (everything north of the fuel pump is new including the fuel pump).since everything is new that hole would have to be in the line from the tank to the pump. It shouldn't be water or krud in the tank since it's been happening for a few years Thanks, I've been chasing my tail on this for so long and can't seem to find a thread that describes my problem [/QUOTE]
