GL: What happed to the Great Loop

[Matt Mattson]

Have you checked the hoses for spongy spots, sometimes they denote an  
area of de-lamination where the inside wall of the hose collapses.   
You might also want to check the exhaust for obstruction as well --  
that should be an easy check with twins.

Good luck!
