My idle has been non-existant lately and i finally decided to find the problem thinking it was going to be the IAC. Well, i don't think it is. I found that by undoing the vacuum line from the Intake manifold to the fuel pressure regulator brings my idle back to normal. if I plug the nozzle on the intake manifold the car dies again. So what could be the cause of the problem?

its suppose to go up when u do that. what motor do u have does it have the idle screw on the tb. are u getting any engine lights

 

Sorry... it's a JDM H22 I have a Skunk2 intake manifold and skunk2 pro cams in it. yeah I got the idle screw on the TB. no check engine lights. car runs good without it hooked up, but when I hook it up it won't idle.

 

open up the idle screw and see if that helps. if its never been moved then u may have to use a impact driver to break it loose

 

anyone else??
