Sticky throttle/nearly stalling WH

[mildewmatt]

Hey guys. I've got a WH V6, n/a.

Just bought her, she's a tidy unit. When it's not been run for longer than about six hours, the throttle sticks. Unjams with a quick blip on the pedal. I noticed in traffic today that it was nearly stalling - revs dropped enough that the alternator light was coming up, but then it brought the revs back up and settled, it would do this every time i accelerated. When I turned off the lights (it was foggy, the fog lamps were on too) it settled down.

I'm thinking I might need to clean out the throttle body and IAC. Does this sound about right? Has anyone had a similar problem?

Thanks,
Matt
