Sticking throttle???!!!!???

[Syclone#1992]

I have had a few issues with the throttle sticking and would like to know where to start looking and if anyone has had this issue.

It is only when I get on it a little bit, but today it was the worst. I ended up throwing the truck into neutral and it finally unstuck itself on the freeway in neutral....what would be causing this? Throttle body? Throttle body spring? Cable.....I would like to fix this ASAP and wondered if you guys had any tips.

I remember years ago Ivan posted about his accelerator pedal getting suck behind the top of the floormat when he stood on it. A building eventually stopped the truck.

At first I thought it was the cruise control coming on, without me pressing the button, but then I turned it totally off. Its kinda scarey when it happens, so I am going to figure out what it is.....

Yeah i work at a carwash and floor mats always present a problem. One time a car went over a curb across a street and into a building before it stopped.

I suggest rotating the butterfly by hand and check for sticking. Had another car do this off idle, and I fixed it by cleaning the crud and polishing the throttle body in the area around the butterfly.

i have seen bushings wear out on tb's before. open it up to where it sticks then your under the hood and see if the shaft wiggles side to side.

I first learn of this on a Saturn. The butterflies on the engine side were caked with engine crud. Any time it came off idle - you'd have to rail on the throttle to get 'em to move. What made this even more fun is that it was a 5-spd. People always thought I was trying to race (sometimes this is true - Saturn > Braphoon).

Although, it sounds like your's is sticking open - could be the same issue.

Rotate by hand and see if you can feel it. If you feel it there - take the TB off and clean it. Carb cleaner works really well for this and provides a nice buzz if done in a closed environment.

Well I took a really good look at it last night again. I don't believe its the mat. I kept trying to get it to stick again, and now it won't. I rotated it by hand and can't find a sticking pointed either. It seems fine, but I don't want to beat on it all day just trying to make the throttle stick.

umm.....any reason why the truck has to be running to test this? I would do it off personally. A stuck throttle sucks. I had it happen (car mat syndrome) w/ my explorer eons ago. It also happened to my ever aging dad the last time i visited him. He has a bmw 330xi, and the throttle got stuck about 3 or 4 times - one time almost shooting us through a gate :lol: Scarey being a passenger when this is happening.

but anyway....don't test it w/ the truck running

LOL, I obviously DID NOT do it with the truck on!!! I rotated it by hand about 20 fucking times (with the truck off) and then oiled every thing, and took it for a ride on the freeway, where I got on it a couple times, and it never happened. I swear its not the car mat though :-?
