Falcon XH XR6 not idling properly

08-17-2007, 01:07 AM

Have had a problem with the XH for a while, where once the revs get over about 2100 revs they either come down very slowly or not at all.

Had a efi expert have a look at it and we replaced the throttle position sensor which seemed to help, but didn't cure it completely (which I find a little strange)

When cold, the motor drops revs like it should, but as it warms, it gets worse, and in summer, you have to feather the clutch in a higher gear to bring the revs back down.

Once under about 2000 rpm it drops to normal at around 800rpm

any help for this frustrating problem would be appreciated
