hi all I've been checking through the engine bay on the 107 and have found what looks like a vacuum solenoid valve located on the back of the air box area. one of the pipes running to a metal line had two big splits in it and was wondering what this will be causing. i have a pic of the part but its not the one in question. i feel the engine isn't running as smooth as it could and have replaced the plugs and coils seem fine so could this cause any issues and what is it cheers richard.
