wont rev up
My 94 grand Laredo 5.2L will crank and idle fine,nut when i try to rev it up or drive it,it just pops,spits& spudders,i have changed more things than i carr to list trying to fix it. Funny thing tho on that venture i figured out i can make it rev up normal when i unplug the throttle position sensor only then it wont idel. When i replaced that part,still no luck:-( does anyone have any ideas???
