Sam063 Posted December 12, 2015 Share Posted December 12, 2015 Hello Wondering if anyone can help... I have a 2004 Fiesta Mk6, has been fine until a couple of days ago when I tried to start it Car will start up but will not idle, as long as I have my foot on the gas car will stay on, however as soon as my foot comes off it stalls Have used machine to get the fault codes it is showing U2510 CAN Communication bus fault. Took instrument cluster out and fiddled with it a little bit and put back in, car then worked for about an hour before same issue reoccured Guessing it is going to end up in the Ford garage and will cost a fortune but if anyone has any idea what this could be that would be a great help as I am totally stuck Quote Link to comment Share on other sites More sharing options...
GingerFlame Posted December 12, 2015 Share Posted December 12, 2015 Things to try; Disconnect the battery for a few hours. Clean the throttle body and idle control valve Check the contacts inside the accelerator pedal box If it's petrol, check spark plugs Coil pack often goes faulty too Check air filter Check fuel filter Check the earth points too Quote Link to comment Share on other sites More sharing options...
