Just done an S2 motor transplant into an MK5 shell, to start with it was overfueling so i unplugged the cold start valve then plugged it back in and now the plugs stay clean as they should and it doesnt smell like shell refinery when running but it still cuts out unless you hold the revs up and it runs a little bit lumpy unless you hold it above 2000 rpm, any ideas? regards. pete

 

sounds like you need it setting up pal.
make sure your A/F meter plate has a couple of mil free play whenyour engine is off.
Am i right in saying you live in wakefield?

 

No mate, im in york but gonna take it to tony in wakefield for a setup but i cant drive it down there like this lol

 

Oh and when it cuts ot you need to relive the pressure from the fuel system or it wont fire again!

 

will it not fire again because it is flooding the cylinders with fuel?

 

yup, sometimes the plugs r wet
