When at idle there is a terrible rattle, it sounds as though it's from under the driver's side. I haven't seen anything on here which seems to be described the same way, BUT I did find something on youtube which sounds exactly like my sound.

That's someone else's video but sounds suspiciously like my sound, also in the past few days it's become less of a rattle and more of a hiss at high speed and now it seems to stutter when shifting into third.

Any ideads?

 

To me, that sounds like something is loose. Maybe a heat shield or an exhaust hanger is broken? I'd get under it and start shaking things until I could duplicate the noise, I'd start with the exhaust first. Maybe your cat is rusted through or it's broken up on the inside? Also check the manifold, your gasket may be bad and the manifold is bouncing in the head. Does it smell "funny"? I'd rule those things out first.

 

yeah-USMarine1108 is right-you should have filmed the right side of the unit though!
Sounds like exhaust noise is covering up another issue as well! Plus I noticed you need a fuel system & ignition check also,these motors should start on the first turn,not 12-15 crank-overs!

 

that one sounds like a lose exhaust
