Re: ZS 180 - Not Slowing Down !!
Already checked the mechanical stuff before I bothered the garage. The throttle pedal returns ok, the linkage at the throttle body is moving freely, the carpet's not in the way, etc. I reckon it's a fuel/air mixture or electronic sensor problem. There's a mention of something similar on the MG Owners Club site where a road test of the ZT makes reference to an earlier test of the ZS. Apparently the ZS they tested suffered from a surging throttle response. Could be caused by the same (unheard of !)problem mine's now got.
