Hello fellow 480 owners,
I recently have a problem with my 480 turbo. When the engine is idling the RPM's go from 800 to 2000 without touching the accelerator.
When I checked the engine I noticed that the throttle housing was sucking air in through a grey round extension on the side of the throttle housing. When I put thumb over the extension the engine runs normal.
When I look in the extension I can see the inside of throttle housing, is this normal? I can hear it sucking in air and this wasn't the case before.
I checked pictures of other 480 turbo engine's and they all look the same as mine engine so there isn't supposed to be a hose over the extension.
I hope someone can help me out with this.
Kind regards.
