800 gs running not so smooth!!

[jimmy mac]

Hi everyone, my 2008 gs8 ,despite full dealer service is kinda hesitating for a nano second at several points during acceleration particularly between 5 and 6000 revs. Dealer gismo not diagnosing any faults!! Anyone got any ideas?? Jim

had the same symptoms. They finally changed the plugs and the fuel pressure sensor. Problem seems to be solved... 170 euros :-( (800GS july 2009)

I think I read somewhere that the engine runs very lean, I could be talking mussi tho',
