Same problem for me. The car would idle at about 2500 when started from cold and about 3 miles on would not idle at all, resulting in the revs dropping off when changing gear or stopping. Also rather jerky in top gear unless thrashed - numerous trips to the garage for air idle valve, injectors etc. but still a problem! Have just found out that GVs are a bit prone to carbon build up in the throttle body - mine was almost blocked - it now feels like a different car.

does it have a cold start injector seperate from the other injectors usually on the upper intake somewhere with a fuel line going to it

this is caused by slow engine idle speed, do the procedure below.
Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

I'm having the same problem, so far what i can come up with is the IAC system ( intake air control) either the IAC valve or the stepper motor that the IAC valve sits on. I have already replaced valve and it is comming up code 35 IAC system. I'm thinking now i have to replace the stepper motor.
