so i had an extra throttle body and had it bored it by this guy that my friend knows.. i out it on and it idles at 2500/3000rpm...i took it off and put my stock one bak on and everything was fine....i dunt think thinks the gasket cuz its the same one i use for both of dem...but there WAS a hosing that goes to a nipple on my STOCK t/b next to the top sensor.....but the bored out tb dunt have a nipple, check the hole it had,doesnt suck or blow....then i check the hose and follow it to a BLACK cylinder under the brake filter...(pvc >? i forget) but it doesnt suck OR blow from the hosing...i dont know if thats the problem ..i always heard i might need to get it recalibrated...is it true? or is it the idle screw?? i try to screw it but didnt move..seem like i was bouta strip it soo i just stop. not i got my stock tb back....

Wow...spacing and actual words really help people understand what youre trying to say.

The reason it idled so high is because you had a loose hose - a vacuum leak.
I cant figure out what hose it is youre talking about, but it either needs to be plugged or spliced in with another hose, if the new throttle body doesnt have a spot for it. (Chances are, you will need to splice into another, rather than plug)
