if not, find where it is binding and clearance it (if the butterfly is hitting the TB, etc). some butterflys allow adjustment to get it dialed in.
good luck.
sorry if you took that personally. i figured you had exhausted other things first. i only said what i did, as some TB's say in the instructions to adjust the butterfly. it would suck to jump through a lot of hoops when a simple adjustment would have cured it (like you tried to do). i speak from experience on doing things backwards. LOL. i have done involved 'fixes' to later find that i could have adjusted something in the first place and it would have fixed it.tonydalrymple said:What I "conveneintly" forgot to mention is the trouble shooting that led up to my little fix. I first thought the factory return spring on the throttle cable was weak. So, i took about 1" of 3\8" fuel line, split it, pulled the spring back off the plate or "stop" it rests against, & zip tied the hose on to increase the throttle return spring pressure. I still had a sticking throttle & it was even more difficult to modulate the gas pedal than before.I then decided the throttle cable must have been kinked in the engine swap(former 4cyl car) & I bought a brand new throttle cable assembly from Ford. Wrong again! I then sprayed WD40 around & under the throttle body; including under the TPS. It would "free up" for a day or two then return to it's sticking bastard self. Finally, a friend mentioned trying graphite. I couldn't find regular powdered graphite at the local store; but they had the spray graphite....

add to this, that having the TB stick at WOT could be very dangerous - i would want to know i exhausted all possibilities and fixed it as properly i could.
so sorry Tony - that was my perspective; my comments were not directed at you
Al: you are sure it is the butterfly that is sticking? i just had to ask. one can disconnect the throttle cable at the TB and test each (TB vs cable).separately.
good luck.
Thats the exact symptoms. I couldn't of discribed it bettermillhouse said:I get that problem from time to time. The cure for mine is to remove the t.b. and clean the snot out of it. I even remove the blade and remove all deposits. The clearance between the blade and the t.b. is fairly small. Just a tad bit of carbon buildup can cause the t.b. to stick. My symptoms were: Hanging idle, difficult to accelerate smoothly, accelerator pedal felt notchy.
Will also try with spraying the graphitetonydalrymple said:I bought a can of spray graphite, removed the TPS, sprayed the area underneath it really well,(yes, your lubing the top of the throttle shaft), & reinstalled the TPS & set it to .97V. Problem gone for the last 6 months...... Hopefully for longer!
