i'll look into that, thx motorhead. the additional problem 'i' notice (realize this is not my post/thread) is a 'search' for throttle response at/with slower speads (occasionally) kinda like a blurp, rump, but give 'er good throttle, she powers right out of it - like she's burning bad gas...

i dumped 2 cans of seafoam (one in each full tank roughly) - we'll see how that goes. I found a 'BG' product that is not available at parts store chains but is available through your Ford dealer. However, it's $30 a can (vs $8 for seafoam) and but i will run a can of it through next tank if i can.
