Hmm well Im almost certain I have all my vaccum ports hooked up correctly, but for some reason when I have my bov port hooked up to my bov the car will not start.... its as though it needs the air from the bov port behind the throttle body to start.... what could be causing this? Perhaps FIDLE, or TPS? Also, if someone would like to run over again where all the ports should go, that would be great.

Take apart yout FIDLE assembly, its 3 screws and 2 parts. Take it apart and clean it see if its clogged up or whatever cause thats where your air for idle has to go in. Also check if the idle adjustment knob is working properly.

Give them a good cleaning and replace the gaskets as well.

cleaned the FIDLE...still the same problem. Will not start when BOV is hooked up. Will however start with the BOV hooked up if the FIDLE adjustment screw is removed.
