Idle problem

[Gadget-Master 2]

Hi all,

Here’s my dilemma:

When I fire up the VR it will not idle properly it will cut out unless I manually keep RPM's. I have to do this until the working temp comes up. When approaching junctions etc; I have to keep low revs on and gently slow down if not the engine cuts out. Also, when driving the engine sometimes feels lumpy; dips power (misfires?). Once the engine is up to working temp everything is fine, runs smooth.

So far the VR has had a new coil pack, plugs, leads, MAF, engine coolant sensor, throttle body off and cleaned. New CAT and lambda sensor. Only 2 parts not replaced are ISV (1 on order) and Cam position sensor; if these don't work I'm stumped!!

To slow the process of insanity does anybody have any suggestions or insight?
