throttle body problem

[tsi95]

the throttle plate in my throttle body is getting stuck whenever i first start the car, but now its starting to do it every time i stop. i thought it was dirty and cleaned it. It didnt help at all. does anyone know what else i can do?

[ashah000]

Check the spring, cable, and the throttle plate.

[tsi95]

i know its not the cable or the spring. its either the plate because i cleaned it with emory cloth or something else

[gthompson97]

try loosening the 2 screws on it and then opening and shutting it so that the plate sits into place, then tighten the screws.

[tsi95]

which two screws?

[gthompson97]

there should be 2 screws that hold the throttle plate into it's holder, loosen them up and open and close it a little and let it slide into place, then tighten up the screws and that should fix it.

[tsi95]

tried it, but it made no change. I also noticed when i open the throttle i am able to move the throttle plate from side to side. is it supposed to do that?

[xavier3jr]

do u have a CAI or did u take ur air filter out i dk if this could be the proablem but could ur throttle plate be bent? or warped

You shouldn't be able to move the throttle plate side to side with those 2 screws in, because that's exactly what the 2 screws are there to do - keep the plate in one place. You I'd say something is wrong either A. throttle plate, throttle plate shaft, or the 2 screws could be screwed (yes I meant to make that pun ).

[tsi95]

the throttle plate shaft moves when i move the throttle plate

[gthompson97]

then either the shaft is broken or the bearings that the plate rotates on are bad. take the throttle body apart and see what part(s) are bad and replace them.

[1stGenRocks]

if you take it apart replace the TB shaft seals too since they dry out and cause boost leaks

[kjewer1]

The seals are also what locate the shaft. Though I dont believe they will allow side to side (or end to end I guess) movement of the shaft. There is a nit on the plate that holds the return spring, and there is a nut on the other end under the throttle position sensor. One of those could be loose I supposed. Either time, sounds like time for a rebuild. There are a couple vfaqs out there for it, read them carefully. Its only a couple bucks in parts, but there are a couple ways you could go wrong with it. Just read and understand, then do.

[tsi95]

im thinking about just buying a new one

[kjewer1]

The dealer is charging 225-300 for new TBs, and if you buy a used one (~100 with sensors) odds are the seals still leak and should be changed. Its only 7 bucks to rebuild the one you have, I would at least consider it. The vfaqs are quite complete.
