under high load (WOT) it wont shift till almost redline. thats normal.

if its running rich its not a vacuum leak. you would be running lean with a vacuum leak as it would be sucking in unmeasured air.

your ignition timing is way off. it should be around -5 (5 degrees retarded) at hot idle and about +15 (15 degrees advanced) at about 2000RPM. the question is why. also the MAF is reading too high. it should be down around ~.4g/s at idle and it should never even hit 17g/s (i dont even hit that at WOT and 6500RPM)

were those readings taken in P/N or in gear?

Readings were in Park. The timing belt does need replaced, it is looking pretty warn. It may have jumped a tooth or two on one of the cams maybe. It flops around quite a bit more that I'd expect.
 
since it does need to be replaced i would say go ahead and do so but i dont think thats your problem. I think the MAF you put in is either bad or not calibrated properly. however i would not waste my money on another reman. i would go get one from a junkyard or see if there isnt somebody else in your area with a 96-97 zetec that will let you borrow the MAF for a quick test run (the advantage here is its a known good sensor). dont forget to reset the PCM when you replace it.
 
I'm going to take the whole intake off and inspect it for holes and see if I can get a MAF from a junkyard to test it. But, I cleaned my old one and it didn't work, got a reman and it didn't work. I'm wondering if a wire somewhere is frayed or something... I can get a better view of everything with the entire intake system off.

Thanks for the help, Striker2, I appreciate it! :)
