-- [ From: human * EMC.Ver #2.5.02 ] -- >So the million $$ question is, how do I find the leak? I asked and this is what I was told (guess what, the coupe failed as well... ) With the engine running, play an *unlit* propane torch around the vacuum hoses. The leak(s) will suck propane into the manifold and cause a surge. Huw Powell
