i have a very similar problem on my 2000, taking it nice and easy and on the flat, the car pretty much drives (almost) as normal, but trying to put my foot down a bit, or going uphill, results in massive revs before the engine catches up, if at all. i'm going to disconnect the battery for half an hour today and have a go at the ICV, been reading everywhere that can help, but i've got a strange feeling it's the clutch, be intresting to know if you or anyone else have solved the problem?
