Throttle body sticking - 2003 Mini Cooper

The throttle body needs cleaned its gumed up.Take throttle body off and spray and wipe the inside of the throttle body with a can of throttle body cleaner this should free it up.If that didn't help then you need a throttle position sensor.Reset the computer after any sensor is changed.

I would have the throttle body professionaly cleaned first. There is a radiator cooling hose that runs to the throttle body that may be plugged and causing the throttle plate to frost and stick.
Have the throttle body cleaned and the cables inspected, that should take care of your problem.
Good luck.

Your best bet is to keep working the throttle. You can *try* to spray a lube such as Tri-Flo onto the braided cable near the end of the sleeve, and see if that helps with working it.
I also suggest taking the throttle cable off of the throttle body, and manually work the throttle body to make sure it's not what's sticking.

I would spray some WD-40 on the throttle cable, also, you may need to clean the throttle body and throttle plate, sometimes there will be some carbon build up that will make the throttle plate stick in the throttle body, Gumout and an old toothbrush works good.

DETACH CABLE FROM THROTTLE LINKAGE..MOVE CABLE IN AND OUT OF CABLE HOUSING..IF IT MOVES FREELY,YOUR PROBLEM IS MOST LIKELY IN THROTTLE BODY/PLATE..YOU CAN REMOVE THROTTLE BODY..FIRST REMOVE AIR CLEANER,UNPLUG TPS,IDLE MOTOR AND INTAKE TEMP SENSOR..USE BRAKE CLEANER OR THROTTLE BODY CLEANER AVAILABLE AUTO PARTS STORES..DO NOT LET AND CLEANER GET IN TPS..YOU CAN USE A PLASTIC OR WOOD SCRAPER..SO YOU DON'T SCRATCH THROTTLE BORE AND CLEAN DEPOSITS FROM THROTTLE BODY/PLATE..HAVE SEEN THIS CAUSE STICKING OF GAS PEDAL..I HOPE THIS HELPS..WHEN DONE CLEANING,REINSTALL THROTTLE BODY AND RELATED PARTS

The throttle-body (or throttle plate inside the throttle-body) is probably gunked-up with carbon deposits and needs a good cleaning.

Take the air snorkel off of the throttle body and look inside while holding the throttle plate open. If you have thick black deposits on the back side of the throttle plate, you can clean it by spraying some throttle body cleaner (Available at any parts store) onto a rag and using an old tooth brush to push the rag, clean all the black gunk out of the area.

I recommend an old tooth brush because using something hard like a screwdriver can scratch the inside of the aluminum throttle body and actually make the throttle stick worse. I don't recommend spraying the throttle body cleaner directly into the throttle body because it can end up in the air plenum where it may loosen some deposits that can cause severe engine damage.

Rust, being old.. aging..

This is due to the throttle flap sticking within the throttle body. The throttle flap is operated by the accelerator cable which turns the semicircular control on the throttle body. Remove the air hose to get access to the throttle body. Use carburetor cleaner to clean out where the flap sits in the body. There'll be lots of black gunk to remove with cleaner on a clean cloth. Reassemble and no more sticking accelerator.

There was a recall on the throttle body blade on the 4.3 a few years back for the throttle body to stick in the close position. Yours being 9 years old makes me think that there not going to do anything for it but give you the solution to the sticky throttle blade.
The solution was to change the blade. You can try cleaning the throttle body blade by spraying throttle body cleaner in to the barrel of the throttle body. If you look down, you'll see the carbon build up and it may just need and good cleaning. 
If that does not work, you can buy a new Throttle body blade which is only held on by two screws on the throttle blade shaft.

Start with cleaning the blade and throttle body with throttle body cleaner. Just follow the instruction and you'll be fine. 
Keep me posted and good luck.

clean the throttle body and flap. with the a tooth brush and throttle body cleaner from the parts store.this should fix the sticking im not sure about your stalling problem. also after you clean the throttle body and flap. it will be hard to start at first until all the cleaner burns out of the engine. its normal and will clear up in a minute or so. make sure you clean both sides of the flap. by holding the throttle open while brushing and spraying into throttle body. good luck.
