Well almost anyways. I have been fighting the mini gremlin ever since I replaced the depression chamber. Well today after Chuck's "everyone should read this post" I was replacing the fuel line and then I found it.<P> <P>The vacuum hose from the manifold to the thermo switch. I was sure this was good because I just replaced the thermo switch. The nipple was broken off. Anyways I'm powering up the hill now at 65-70 in fourth. Time for those 31's. I never new my 2.6 had so much power....well it's not my former 67 Camero but it will do.<P>It seem that there was just enough shift in weight while going up hill to cause the hose to bend just enough to open up the break, letting the vacuume escape.<P>Les
