It's a pretty easy job to do the rear.
Took me about 2 hours and I've never replaced plugs on a Escape before.
I took the trottle body off, it was a lot easier than unhooking everything from it plus I left a few hoses attached to the intake and just used a coat hanger to hold it out of the way.
I wound up reusing the old intake o-ring gaskets because they looked in good condition, I also replaced the PCV while I had everything apart. |
