crazy idle problem

ok so....my friend just bought a throttle body spacer for a 00, sedan dx and a quick shot of nitrous ( like a little 30 shot that is hand held) so i told him i would help him put it in. So we put everything in and now whenever he starts his car, his car just keeps reving and we have to turn it off or else it will keep reving. we checked all the vacuum lines and all the sensors and everything is pluged in as far as we can see. could we have adjusted the idle very high on accident when we tookt he throttle body off??? or smt of that nature???? so any feeedback would be greatly apreciated thanks

little screw on the top of the tb, its covered by a little black tab, turn it counterclockwise to turn the idle down. might just be the spacer, i never really saw a use for those

leak in the gasket?

ya we were jsut trying it out to see if it will do ne thing we'll let u know how it turns out if we can ever fix our problem but for now we just put it back to stock and now its throwing codes so we haev to figure out what they are now thanks for the feedback
