Revs not falling off straight away after releasing pedal

[krash67]

Guys,

Can anybody shed some light on this, could it be slight stiction in the throttle body? also noticed idle revs slightly erratic when it comes off warming. Seen cleaning the TB cured the idle revs, but could they be related.
Just fitted new KTEC induction, done a full service & cam belt change.

Mine is the same mate. I believe it's ktec's induction related. Only when it's cold though and it lasts for a few seconds.

Thanks, but it as been warmed up and when you give it big amounts of right pedal.
