Re: Throttle is sticking.7000 rpm
Clean inside throttle body with intake cleaner and a rag may be sticking because of gum and varnish buildup in take manifold. This should work, if it doesn't then you will need to check cables and make sure they are not locking up and moving freely. If that good then Throttle body will need to be replaced because this can be very dangerous with it sticking like you described. Good luck and thanks for using FIX YA

The throttle body can be sticking. Also you could have a broken throttle position sensor. Vacuum leak, near the rear of the intake can cause increased RPM's. Check around under the hood for loose connections, I always start there.
the idle control motor could be opening up causing the rpm to increase(acting like a vacume leak),by either sticking or the(ecm)computer, is commanding an increase in rpm.a bad throttle position sensor ribbon could be the problem(must be replaced no repair).if it was a sticking gas pedal then at idle when you move the gas pedal the rpm`s should increase alot.its possible that a vacume leak could cause this like a hose,although this should show up at idle with a high idle.
does it stick in the cab or on the throttle body? make sure the cable is wrapped around the throttle linkage properly first and then id spray some wd40 on all the moving parts down by the pedal. sometimes gunk can get built up in that area and it just might need a good cleaning. odds are pretty good that the moving parts are really dirty or the cable isnt lined up properly on the throttle linkage. id start there.
I had same problem on my 2004 lesabre, I waited until it was stuck and opened the hood and pulled on the throttle by hand very easily and could feel it sticking there, so I sprayed carb cleaner on the springs and around and through them. This loosened it up right away and have not had any trouble since, I did not spray anything into the throttle body, Good luck
a manifold leak ,dry-rotted vacuum lines also contribute to high rpm ....is there any visible signs of gasoline on the ground try using a piece of cardboard to see if any fluid gets on it also open the hood and check for visible leaks or missing cracked vacuum lines etc but sounds like a vacuum leak
