Got my self a problem with my Scooby I was driving went to put my foot down and it just died on me I pulled over tried to start it and it would run really bad and when I tried to rev it she just cuts out it seemed to me that it could be maf sensor because when I fitted my new air induction kit I forgot to plug it in and it run lumpy so I checked that and it seemed ok but I unplugged it and it runs it won't rev over 4000rpm and the engine management light come on and it went into limp mode but it got me home I thought it would be the Maf sensor so I changed that but it still the same any ideas please help
