so i bought a 66mm throttle body from skunk 2 racing about a year ago and I was having a few problems with the idle and other stuff like that. After the VAFC II and tuning and replacing a few other vac lines and other stuff my throttle still stuck a bit and the engin would stick around 1500 to 2500 rmp. called skunk 2 and they said it was "normal" and to just set my idle at 1000 rpm so it would have enough "spring" to close the butterfly or something like that he told me. well I didn't want it to idle that high and left it set at stock stetting but lately witt the hot weather it has been sticking more and more. It's really anoying espically when shifting (it sound like im power shifting) so i was thinking of taking it off and honing the inside out just a little but with some very fine sand paper. good idea or bad? let me know

 

i think you should just follow skunk 2's advice. what kinda engine do you have btw?

 

agreed

 

you also might wanna ditch the afc tunes ... get a real tune

 

by the throttle being stuck do you mean the pedal was stuck or the idle was stuck at 2500?

first off, the idle should never be adjusted with the cable. i know you didn't say that but that's what it sounded like skunk2 was telling you.

set the base idle at the right spec for the car and the iacv should do all the rest. if the iacv isn't clean it will have problems doing this so make sure it's cleaned. depending on which motor it is you may need to look at the fast idle valve.

 

its only the D16Z6 (and I bought a bigger TB at the time bc I was planning on boosting it now I've seen the light of a swap. ya!) Choosing the VAFC was based on money at the time and I woudl have loved to have goe wit Hondata S300 but I didn't have the extra few hundred at the time and the engin needed to be tuned or I was going to risk loosing it. By sticking I mean the butterfly inside the TB sticks just slightly to keep it in the higher RPM range at time and if I slightly tap the gas peddle it is enough to close the butterfly completly and the idle is back to normal. It doesn't sound like a big deal after putting up with it for a year and having to blip the throttle in a parking lot or some other place and looking like a ricer revving the engin it needs to be fixed. thanks for the responses but nobody has really stated if it would work or they have done something similar.
