ok getting to the niddy griddy I have a 91 F-150 with the I-6 in it. It has a really awful miss only during light throttle and when you push on the gas slightly in Park. This has been going on for about 10K miles or so and it's not gotten more worse nor better. The catalytic converters went to hell, and that didn't affevt the miss. Here's what I have done and what a waste of time and money:
I have done a complete tune-up: plugs, wires, cap, rotor, fuel filter, air filter, breather filter, and adjusted ign, timing to specs. and replaced 02 sensor and reset the computer by leaving the Neg. battery cable unhooked for 30 sec.
This miss my truck has is really pissin me off really bad and I'm about ready to say the hell with it and set it on fire
PLEASE HELP ME!!!!!!!!!
