[gronows gti]

i have a golf gti 1995/n 8v only had it 2months nothing but problems cutting out and now doesnt like starting again when hot.i am new to this website and vw's.i have changed the usual things plugs,leads,rotor arm,dizzy cap,fuel filter,battery.And more recently ecu relay and fuel pump relay as read on this website.any other ideas would be great cheers to all

just a thought, but is the breather on top of the rocker cover split? mine was, and it was a b!tch to start... don't rely on VW to supply the right part, i ended up using a random piece of hose and superglueing it in place, starts first time, every time now, and the smell of oil has gone too....
