I took the throttle body off of my 2nd gen b16 and when I went to buy a new one, for the 99 Si it wasn't big enough to accomodate for the fast idle thermo valve. I tried a gasket from a the del sol si and it was the same gasket and it didn't cover the whole thing. Ok, now that I put it back together without a gasket whenever I drive it and then let off the gas and the butterfly closes the throttle sticks shut, because there's no gasket in there. My question is, what gasket should I try?

 

Anyone?

 

i completely lost you in your post. what tb (throttle body) are you using right now? and what kinda im (intake manifold) are you using too. if you are using a stock b16 tb with a b16 tb, then get a b16 gasket. i have one for sell if you want. dkhuynh@gmail.com

 

Use a '94 to '95 Integra GS-R gasket. It's a little bigger ID, but that won't matter. it'll have the proper holes for the FITV and IACV ports.
