Hi, I had the same problem last week. See the topic: http://www.ukstarletclub.com/forums/index....mp;#entry511462 I sorted my SR out by taking the TB off, remove all the sensors and then giving it a good clean with some carburettor cleaner. I made the mistake of using WD40 first which made it worse. I also disconnected my battery for about an hour which reset the ECU. Hope this helps Shahzad
