Bigg_kayz Member 111 Member For: 9y 7m 3d Gender: Male Location: Perth, Northsider Posted 29/08/15 10:56 AM Share Posted 29/08/15 10:56 AM BA mkii xr6t ute 500rwhp - heavy duty twin plate clutchAfter my recent retune ive noticed that when I push in my clutch the revs dont drop to idle point... the only time I reach idle revs is at a stand still.say if im cruising at 80km/h and put into neutral or keep the clutch depressed the revs will drop with the speed ,, why would this be? Its even worse on cold start and im finding when cold the revs jump around a fair bit , some times ill even get a stall if I try take off after first cold start in the mornings, never had this issue with other xr6ts or tunes??

Also had a rough idle on cold starts. Turned out to be a leaking intake manifold gasket. I Replaced it then found a new tuner as mine left the shop like that! Thanks to c&v...

chris_richo Member 8 Member For: 13y 7m 14d Gender: Male Location: port macquarie Posted 14/09/15 11:14 AM Share Posted 14/09/15 11:14 AM Sorry for the late reply. Mine leaked where the intake manifold bolts to the motor coz the gasket was stuffed. U can check for leaks by VERY CAREFULLY spraying some throttle body cleaner or wd40 around the manifold, if there's a leak there will be a slight drop in revs. I'm no mechanic so there might be a safer way of checking for leaks. Maybe the manifold bolts need to be re tourqed. Good luck keep us posted Link to comment Share on other sites More sharing options...

It seems to be the same gasket as you described as the nizpro plenum side of things is sealed. Link to comment Share on other sites More sharing options...
