i have a acceleration problem with the runner it acts like a carberator car without the acceleration pump ,i have changed the fuel filter , fuel pump , fuel pressure regulator without solving the problem . the runner only accelerates and runs good when i have the return fuel pressure line mostly kincked off . this whole thing just started one day , no apperant reason , thought it was bad gas from local sams club which started the insanity.
