Angry Gas Pedal keeps sticking!!!!

On my 02 F150 Screw Lariat my pedal sticks for about 1/4 of an inch to a full inch when I push it! If I tap it when I go to push it, it doesn't stick but if i just push it, it sticks and then it gets sets free and throws me and my passengers back into our seats. It's very annoying and it's getting worse, I have no idea what to do. ANY HELP would be much appreciated!

Clean your throttle body. It probably has carbon near the butterfly plate and so the plate sticks when it's closed.

correct on TB cleaning. not that hard to do. heck i think it can be done with it on the truck... just get some cleaner, old toothbrush and scrub. while you're in there get some MAF cleaner and clean it.

Berrymans b12 is the best cleaner but I'd remove the throttle body to clean it out real good. Might also help to remove the cast-aluminum elbow that goes from the throttle body to the intake manifold and clean it as well.

Also, check the springs. If I remember correctly there are two throttle body rebound springs - one on the throttle body itself and another that connects to the throttle linkage to a bracket on the intake manifold. One of those may have come loose.

Frozen (Literally) Throttle

FYI...I went to clean my TB last year when this happened and there was nothing to clean. No build up or anything around the butterfly to indicate a potential problem. Now that the temp has really dropped around here, my truck has already started doing it again. I'm used to it now and it bothers me even less now that I know what it is. Plus, once the motor warms up, it quits sticking.

I think some of you guys in the colder climates might want to spray some liquid graphite on the tb cable ends and work the cable back and forth....some of the times moisture can work/wick its way into the cable sheathing/cover then freeze on cold days not allowing proper cable movement/sticking...until the engine compartment is warmed up....

You don't want to spray any lube that going to gum up in colder temps either....

If the above doesn't work one may want to try a new tb cable too.....

Maybe try some lubricant on the edges of the throttle plate?

I had this happen to me before. What it was for me was the spring on the throttle body wheel attaches to a plate so that when you let off the gas the spring will pull the throttle closed again. Well the spring came off the plate so when I gave it gas the throttle wouldnt completely close but if I gave the gas pedal a quick blurp it would be ok so Im guessing it just pushed the spring out of the way but from driving and moving the spring would make its way back to not letting the throttle close. Pull off your intake cover and have a look. long shot but you never know.
