Reviving an old thread!
Motivated by a 1300 mile round trip coming next week, I finally replaced the original spark plugs and wires in my 2002 ST at 127,555 miles a few weeks ago. I've had the plugs for several years knowing it needed to be done. The gaps on plugs 1-3 were around .072, while 5 & 6 were .092 and .096. (I dropped #4 as it came out and still haven't found it.) The worst part of the job was getting the wires off the plugs, and getting the new #2 plug started in the hole. With the tire off, you can see the plug and hole, but there's not enough room to get my hand in there. I ended up using the boot off one of the old wires to get it started with my fingertips.
I've been getting around 15-15 1/2 mpg locally - sometimes 16. I drive a mix of short highway and interstate and city driving, although very little real stop and go. It got 17.1 on the first tank with the new plugs and wires, and almost 17.5 on the second tank. That's with the topper and roughly 200 lbs of tools and stuff in the back. On previous interstate trips from Des Moines to St Louis or Kansas City, it's gotten 18 to 19 mpg. The trip next week is to Columbus, Ohio, which will include a long stretch of pretty flat road in Illinois. It'll be interesting to see what the mpg will be on this trip!
In the past couple of weeks I've also
Replaced the fuel cap
Replaced the foggy headlight lenses with a perfectly clear set of Ford lenses I found at the salvage yard at some point.
Replaced the battery cable terminals.
Cleaned the MAF sensor.
