couple of issues...

first being when i dab the acc pedal and sharply remove my foot the enginerevs ok but dips very low on the run down almost to stalling point some times then rushes back up to about too 1500-1700rpm then idles fine again..
did have a mishap where the idle control valve was fitted wrong way round which was fixed immediatly and have since got a new one and had it well cleaned out and fitted along with new breather pipes.. yet still the same issue, it has only developed the problem in the past couple of weeks and is starting to peeve me off along with my second problem.
i get a rattly sound when clutch engages sitting stationary, when i am coming down through the rev the car gets the kangaroo syndrome.. im not sure if this has anything to do with the cam and maybe i need too adopt a different driving style like revin higher an changing sooner?

Dirty butterfly and a worn clutch release bearing?

May be a bad throttle position switch (Idle switch if applicable) or someone has fiddled with the idle stop if the car is using a throttle position sensor.
