I took my 1.6 VTR coupe to the garage late last week as it was misfiring and the engine management light had come on. They found an injector problem, fixed it and said they couldn't turn the light off though, so I probably needed a new ECU. Car felt better but still misfired. Today it was much worse and I opened the bonnet. First thing I saw was a hose lying on top of the engine, broken. Can anyone identify what it is? http://www.users.madasafish.com/~alexis/engine1.jpg http://www.users.madasafish.com/~alexis/engine2.jpg
