Hi I need help how to fix. When idle the revs are going from 1k to 2k, 1k to 2k and so on. Also like when clutch fully down. Have cleaned the IAVC and throttle body and reset ecu but made no difference. I haven't tried adjusting FITV because I'm not sure if it has one, it's a stock B18C4. There is hissing noise coming from under where I've put AEM fuel pressure regulator. Since this problem, the car feels but jerky when clutch halfway up like it's dragging forward and VTEC is temperamental, sometimes doesn't work. Also have leak coming from either VTEC solenoid or inlet manifold gasket, had this happen before idle issue.
