No. the clutch is not the fault. It wouldn't raise the rpm. Not as far as I know.

Cruise control is a function of the engine ECU and the electronic throttle (drive by wire) on the 2.6  :y (hence cruise is just a software setting in the ECU and does not need an actuator)

On the original fault, check the throttle body carefully.

I have seen it where the throttle body stop has been adjusted to mask a stalling issue (usually down to an air leak or cruded up throttles), consequently the DBW control cant close them enough when idling.

Easy to check, adjust the setting until the throttle butterflies can be felt to stick and then wind the screw in slightly so they don't, lock off with the locking nut.

It has had a live data read while driving, but intake was reading perfect, the guy couldn't fault it, but we was looking for something else and not the rpm fault, may have to go back for a live feed and see if we can dictate why its behaving like that, its been 2 months the car has been driven but still doing it, anything to do with the clutch atall do you reakon?
Only if you are pissed ::)

It's all down to the ecu... Swapping the ecu temp sensor for a new one might help.
