Car = 94 530 V8 Auto - Engine =M60
This engine which I have now had for 2 years has always been the smoothest I have ever known. When idling you can normally barely sense that it's running.
Recently idling is becoming rather "lumpy" - I sense a sort of mis-fire and occasionally it will falter and stop. At all higher speeds the engine feels fine.
So far I have cleaned the spark plugs which look as good as new.
Should I be looking for an ignition or a fuel problem ?
