Whats up with the car as im no help being miles down south. If you cant find anyone and want to get your own tester gendan and ross tech sell them pretty cheaply.

basically, somtimes the revs go mad, jus drop go up and down for example while waitin at the lights, if im not at my bite, the revs go down to 500 and back up 1000 and the car wants to cut out or does cut out, changed 2 spark plugs yesterday and car seems alot better 2day might have been them, or i messed with the wires as well tightening them so could have been that

also im seen "vag com" on ebay, software and lead for around 40 maybe less, is it easy to use?? thanks
