So when they modify the stock throttle bodies they remove the bearing and
use just a plain bushing? I know there are bearings on the side, but was
pretty sure the one in the center wasn't an actual bearing. And you are
crazy if you don't think the vacuum from the engine adds extra force onto
the throttle shaft which is why it only sticks with the motor running. And
the force of your foot pushing on the pedal applies more of a twisting
motion, where as the vacuum from the engine is pulling straight down on the
shaft as the air is forced past the throttle blades. But physics was one of
my better classes in school.

Considering that it's a sealed bearing and floating in the middle, I doubt
he "cleaned" all of the lube off of the TB shaft. I can stick a TB in the
solvent tank for a few days and it still works completely smooth. The
amount of pressure used by your foot to move the TB shaft is way more than
what the engine even puts on the blades under high vacuum.
What does the cable look like? Is the throttle cable mis-routed? What
about the foot pedal bushings? Is the spring broken/misaligned/slipped on
the throttle shaft? Did you mess with the idle stop screw?

Sounds like you "cleaned" all the lubrication off the throttle blade shaft.
Get some anti-sieze and work it into the bushing in the center of the TB
between the blades. You will have to open the blades, and there will be
just a little side to side play so you can put on some of the anti-sieze and
then work it in wiggling the shaft back and forth. The reason it only stick
with the engine running is the vacuum from the motor puts extra force on the
throttle blades which causes the shaft to bind more than with the engine off
and no vacuum.

Subject: DML: Throttle stuck after TB cleaned
Well, like it says, I'm having problems with my throttle "sticking". I
cleaned my TB like I do about once a year, so I've done it a couple of times
before. When I put it back on, and start it up, it's fine. The throttle
pedal feels hard to push through, and when I do give it some gas, it revs
up, but won't come down. I can go to the TB itself and move the throttle
controller itself to get the revs the lower, but that's the only way. If
the Dakota is off, the pedal feels like normal. Did I put the TB back
together wrong (it has the 3 components that go on it - TPS, etc)? I've
looked at all of the linkages, and everything looks like it's hooked up
fine. If I rev it at the TB itself, same issue, but again, I can force it
to lower, but won't do so on it's own.....
