Hi all, little help please.
I’ve got a 1999 z3 1.9 and really enjoy working on the car. Have code cylinder 1 random misfire. Mpg is horrendous, strong smell of petrol, lack of power and sounds like a tractor.
things I’ve changed.
valve cover gasket as cylinder 1 spark plug was covered in oil (solved now) also several hoses that were perished.
all spark plugs
all injectors and fuel rail
fuel pump
fuel filter
crank position sensor
Next step is injector coil and Leeds.
is there anyway of checking the coil pack and Leeds to make sure they are functioning properly?
