I had a high rpm(1400) in park. I found after searching for leaks that the rubber boot between the throttle body and the intake was unattached and sucking in air through there. I now attatched the rubber boot and tightened up both clamps and now the car idles correctly but in park I cant rev up the engine. It sounds like its bogging down. The throttle adjusting screw was turned all the way down by someone prior to me that was probably trying to fix the high idle. Do I need to open this up now that I attatched the rubber boot? Does the screw increase air or?? Thanks in advance.
