throttle body

[pa4ul]

okay i need expert opinion i took my car to a mechanic because it had been studdering for quiet some time. 2003 audi a4 1.8t. he called me today and told me that someone had filed down the butterfly valve in the throttle body. he said in order to fix the problem he would have to replace the entire manifold and valve because they come pre calibrated from audi. is this true or is he just trying to get me for more money. if so how much does this part cost or can u purchase the butterfly valve alone. if u need more information on my car ask and ill tell i just need this problem fixed thanks.

The throttle body can surely be purchased by itself! The throttle plate is part of the TB and I dont believe can be replaced seperately. I do have a bad TB that I will sell you the throttle plate out of if you would like

how hard is it u think to just replace the plate? they guy said the grinded the plate down to maybe try to get more air in the mixture. how much for old tb?

kinda thread jacking, but sometimes my idle is between 800-900 and I keep getting "idle higher than expected.." When I tap the gas at idle, it'll usually drop back down to 800.. Sticky TB in need of a cleaning?

yea u probably need to tk off the throttle body and get the spray cleaner im not sure what its called but theres a thread around here somewhere on how to do it., check the diy section

the plate is easy to replace, just pull out the throttle body and theres 2 set screws holding the plate in place

You may try cleaning it but I would venture to say its not going to help and you may need a new TB

so does anyone know if they are calibrated from factory?
