Hi Folks
Thought i'd post this in here as I cant seem to get any sense anywhere else google etc.
After searching high and low and looking at a number of different cars my missus eventually found a Cooper S that was tidy, full service history, seemed absolutely perfect, drove nice and didnt have any problems at all.
It however has now developed a problem
when it's warm it idles at 1500rpm and sits there for 10secs then rises to 2000rpm then drops straight back down to 1500rpm then repeats. It's as if someone is holding the accelerator slightly so it rises then takes their foot off so it drops back to 1500rpm.
The car was spot on during the test drive which was around 15miles which got it up to temperature it was also fine after the drive home which was around 170miles and again completely normal during that evening after she took it round to show her friends etc. It started doing it earlier on her way back from work.
I originally thought it had an air leak or vacuum pipe blocked/unblocked etc but it only does it when it's warm/driven for a few miles. Does anyone have any ideas or have any previous experience of this on the Mini? Before I take it to the dealer as there are no specialists around this area
I can honestly say this has not been my week for cars
Ben
