Volvo V40 2.0T - accelerator "sticking"

synchronised

Sounds like a sticky idle control valve. It's usually cured with a blast of carb cleaner. The valve will be somewhere round the throttle body - looks a bit like a small electric motor.

Thanks, Carl, I'll give that a go and see if it helps.

Thanks, I've tried this and it certainly does seem to have improved matters - I'm sure that the problem was reliably manifesting itself before (most often when driven before the engine is up to temperature) and it doesn't seem to be doing so now.

I think I located the valve - the throttle control assembly has a cast pipe into it that has something looking like a small motor/solenoid about 2" further back. It's mounted perpendicular to this pipe & is cylindrical, about 3" long and 3/4" diameter, with connectors at one end. There is then a thicker hose that seems to go back to the top of the radiator (where it actually goes back to is obscured by a plastic shroud across the whole top of the front) - is this the idle control valve?

I sprayed the carb cleaner liberally around this lot - should anything have been dismantled beforehand? It seems to be closed to the outside world, so don't quite understand how the cleaner would have penetrated.
