Warning/ FYI Ford lemon, non-recal issue.
Went to look at a freinds 2005 Escape, crank no fire complaint. Had spark at one of the 3 accesable COP up front, all plugs soaked. Swapped COP's around with all partialy firing on the middle signal wire from PCM, good power but bad ground signal from PCM....ouch!
Came home just now to find people from North America to Australia sceaming about PCM inj driver failures on the 2005-2006 Escapes. Correct repairs include 6 new coils, 6 new plugs, wiring harness and PCM. Happens around 88-92k miles just out of warranty, $2100 repeat failures common complaint.
If you have one run the correct SP417 plug only! I would sell one if you have one, ticking time bomb that can leave you stranded at any given time (usualy when cold out).
