i just installed an itr intake manifold on to my b16a and now it doesnt want to start, first i started my car it idled to 2500 then it bogged out and turned off....i capped off any vacuum nipple that i wasn't using, took my time peeling out the old gasket off the block and installed new ones.........do you think its a vacuum leak? i also bypassed the fitv, but not sure if did it right..i just looped the hoses that was connected to the fitv togethter, is this right?

 

Are you sure your TPS, MAP, and IACV plugs were reconnected in the right place?
