anyone know what causes sudden lack of power on the m40 318i engine ? this usually leads to brown trouser moments in rushhour - its always totally out of the blue might not do it for weeks then one day itll just do it with no warnings - well keeps me on my toes, ive tried changing allsorts - idle control valve - cleaned all the inlet side - fuel filter etc etc etc, fuel pump relay, never known a problem like this thats so hard to diagnose - it happens so rarely - altho seems to do it more with the tank quarter full (im suspecting fuel pump pickup or something) but then that was proved wrong the other day too!! - im at a loss to what it is - enjoying the car tho - costs me next to nothing to fix.
