R32 Gtst Strange Idle

[Kwyjibo]

Hi,

I've had the R32 for awhile now but have never bothered asking this question. It idles very strangely, once it is warm it settles to 700 rpm neutral. If I drive it cold and then change it to neutral just as I come to a stop it revs quickly to 1200rpm then drops straight back to 700rpm, however once it drops to 700rpm in neutral once it is perfect from then on whenever I change to neutral. I understand it is normal to rev higher when cold but it revs very high for only a split second then drops to normal.

The strangest thing I've noticed is that the car idles higher if in gear or while moving. When coming to a stop I can have the clutch in and it will idle at 1100 RPM, once I've stopped it might drop to 900 RPM, then when I change to neutral it will go back to 700 RPM. As soon as I put it into 1st it will rise to about 900 RPM again, the only way it drops to 700 is when I'm in neutral.

Does this happen to anyone else? Anyone know why this might be happened. I've cleaned AAC, IAC, AFM, I've adjusted TPS and CAS using a laptop connected to ECU so I have know idea why it does this.

Thanks for the help.
