SupraHuman Posted June 17, 2006 Share Posted June 17, 2006 P.S the idle screw is a tiny allen one just next to where your throttle cables hooks up to the throttle body. Link to comment Share on other sites More sharing options...
Ian C Posted June 17, 2006 Share Posted June 17, 2006 Perhaps there is a hose off somewhere that is allowing air in past the throttle plate... You shouldn't ever have to adjust the idle screw as it's all controlled by the ECU and the idle control valve. that's just masking the problem. -Ian Link to comment Share on other sites More sharing options...
