My mates gti-6 managed to shear a cam pulley about two weeks ago. He bought a new head and put it on today, aswell as doing the gasket, water pump, timing belt, head bolts etc
The car fires up and will run with a lot of throttle but wont idle. With no throttle it will run then cut out after 1 second. He took the plugs out and said they look very rich. I doubt its a sensor because the car ran fine 2 weeks ago.
Any ideas why its not starting?
Cheers
