Recently got my first RR, 2014 4.4V8 autobiography, and now have a problem. Turned into a lane, accelerated and the car then took off by itself, as if I had flored the throttle. Manage to stop and switched off and when restarted was in resricted mode and had lumpy tickover. Got home ok and now just has a lumpy tickover, otherwise drives ok.
Diagnostic scan said faulty MAF on bank 2. Couldn't see how that would affect tickover, so swapped the MAF'S around, cleared codes but same fault came up. Ran a live data stream and MAF on bank 2 started reading fine above 2500rpm as you would expect. Reads 0 <2500 rpm which I assume is normal.
Any suggestions appreciated.
Simon.
