It does seam sometimes I end up with somthing like that, it cant be the simple fix, has to be the bizzare one. Just my luck. But I thank you, never thought to check the vac. For another reason I was going to install a direct mount vac gauge, just havent gotten around to ordering one yet. But I may do that before I jerk out that other dist.
10-4 on the hot day / hot engine! And that's another reason I always hook up a vacuum gauge! Can tell you so much with so little effort!
