    lately the truck has been running a little rough, it starts and idles a little rough and when i accelerate from a dead stop it sputters for a second then gets up and goes and it cruises just fine and while cruising if the pedal is tromped there is no hesitation, thoughts?

    Do you have dual fuel tanks? Our 1990 F150 would do this if we were running off the rear tank, filter was all plugged up.

    yea it has dual tanks but i run the front 90% of the time, actually i'd probly be afraid to run the rear now cuz its been so long

    my injectors are also really loud, could one of them be clogged up? ive put several bottles of cleaner through it in the past but it didnt heelp the sound or the idle then

    Is your cap on tight? Or have you been down any rough roads? If you're timing is off that could be f*cking you up too
