Hissing sound?
I can hear a loud hissing type sound when I accelerate. I have a 1.4 8v 1998. I've checked the air filter box and all the pipes from and to it. When I took the filter box out I noticed the alternator belt isn't central on the tensioner. It over hangs it by a good 5 or 6 mm. May not be related but thought I'd mention it any way. Any advice would be appreciated greatly. Thanks to those that helped with my other problem.

Go to the side.where the egr valve is there is a vaccum pipe there which can sometimes perish and split
If it ain't green and black send it back ![Very Happy :D](./images/smilies/icon_biggrin.gif)

Check the exhaust, a blown exhaust can hiss like a.prick
Easiest way to check is when Cold put the palm of your hand over the tail pipe so it's air tight and you'll be able to hear if it's blowing or not
Check intake piping aswell

If it doesn't fit,
force it,
If it breaks,
It needed replacing anyway![Thumbs Up :thumbs:](./images/smilies/icon_thumbs.gif)

Re: Hissing sound?
I'll check them later, it seems to idle high, about 1800, when I first start it. Could this be linked?
