Have an 03 BA XT, and thismorning when I started her up it almost stalled in Neutral. I kept the revs up for a while and waited for the car to warm up a tad then drove off, but every set of lights for the first half hour of driving I had to keep my foot slightly pressed down on the accelerator. It eventually stopped but worried this could become something more. Any reason its doing this and how much to fix? Couldn't come at a worse time as I'm planning to sell it pretty bloody soon.

Clean your throttle body out with carbi cleaner and a rag.........
