Cutting out at idle revs

Any advice please , my v6 has started cutting out when at idle . I’ve adjusted the Rev speed screw so it’s not doing it but obviously the revs are now higher when stationery . Is there an underlying problem? The engine runs spot on

Strangely enough one of the more common reasons for this is the coolant level not being correct.

Did you check the coolant level and adjust the
Revs with the diag box linked

Where do I get a code reader for a probe lol
I’ve got a canbus reader but the fitting is different

And just check all the 'mechanical' things work really nicely.
Make sure that the ball-race that runs in the slot of the throttle quadrant IS turning and not sliding in the slot.

As said check over for air leaks etc,to do base idle just link Ground and Ten in the
Diag box (when warm) and see wot it does then use the adjuster on the Throttle body screw to adjust
this will also tell if the TPS is out of line

Use a piece of insulated wire and an LED light.

You can make a code reader out of a peice of wire and a bulb . I hard wired one into mine years ago and fitted a rocker switch under the steering wheel .
