I've recently been noticing a fuelly smell inside the car when giving it some, most often at lower speeds, like full throttle out of a roundabout or out a junction or similar.
Doesnt seem to be as obvious when at full throttle on the motorway.
Cant really see anything untowards under the bonnet, no obvious leaks etc.
However i have noticed that around all four injectors looks "grubby/oily" with the rearmost one worse looking than the rest.
Anyone had something similar? My only thaughts atm are that the injector seals could be leaking slightly, blowing out some fuel/air when on boost?
