Hi All, Had my A3 for a few months now and besides a snapped mount on the exhaust she runs a dream EXCEPT...... On start up she idles around 1750 - 2000 rpm's for a few minutes and then calms down? This pi***s me off as the she feels jerky and kangaroo's? Also after I have had a good 'boot' she has the same problem? Feels like a slight hesitation very much like a kangaroo feel again? The exhaust rattles like a bad tempered snake at the best of times and the idle/kangaroo effect seems to be getting worse! IS IT LACK of compression? DO I NEED A REASON to tell the wife I'm getting her re-mapped? Please any help out there?
