vinnyvangough Posted March 29, 2012 Share Posted March 29, 2012 The revving will more than likely be the Idle Control Valve (ICV). Needs taking off and cleaning Quote Link to comment Share on other sites More sharing options...
stevie123 Posted March 30, 2012 Share Posted March 30, 2012 Take off the throttle body and clean thoroughly in petrol or thinners, also clean out the idle speed control valve or get a new one. The problem could also be the throttle position sensor which bolts to the side of the throttle valve. Not too sure about the rattle, could it be the clutch, or release bearing rattling in the gearbox, also check gearbox oil level. Quote Link to comment Share on other sites More sharing options...
