A few questions

You could try out a leakdown test. I know the AC, and power steering brackets are not the same as a fox.

The easiest way to do a comp test is to pay someone to do it for you.

A tester (30-40 bucks U.S. currency) includes instructions. Real short version: Hot motor, Pull all plugs, Disable ignition, Hold throttle at WOT. Vibe has a tip that he puts a charger on the battery as he does the test to keep the cranking the same throughout the test.

I do each cylinder twice - first time dry and the second time wet.

I would be pulling codes first and going from there. If you have a paperclip you can yank codes on US cars (I think it is the same for all NA cars).

Good luck.

Here ya go if you want to know how to pull codes. http://fordfuelinjection.com/?p=13
