Post Advanced Engine Tune up ideas for 3.0

So I have a 2000 3.0 with 138k on it. 5 spd supercab. I just got a few weeks ago by a negligent ex owner... I plan on a long 700 mile round trip in a few months, along with pulling a trailer. And just want my baby to run like a top! and help improve MPG

What I have done so far.
Oil / filter change
fuel filter
air filter (Napa gold till I can afford K&N)
radiator flush / new thermostat
PCV Valve
plugs & wires
serp. belt with new idler & tension-er pulley
(Unplugged A/C so clutch no longer kicks in and robs extra power)



What else can I do without breaking the bank to freshen my baby up!
I'm saving for a new Coil, to see if that helps idle and smoothness.
I'm contemplating tampering with the MAF & Throttle body.
Also what about EGR?
Running Seafoam Injector cleaner?
O2 Sensor? - (If so, wheres it located?)

*Oil and Filter
*Fuel Filter
*Air Filter(Look into the Accel Cool Blue Filter, half the price as K&N but the same thing)
*Clean MAF Sensor
*02 Sensors(The front 02's are more important than the rear, so id only change them. The front controls fueling, the rears only let the computer know if the cats are working)
*Change Tranny Filter and Fuild!
*Change Rearend Fuild
*Dump a bottle of Seafoam in the tank( I do a bottle about every 3K)
*Plugs and Wires( ONLY MOTORCRAFT PLUGS)
*There is no need to change coils, i never heard of them weaking. They either work or dont.
*Check air pressure in the tires AND SPARE!

I did all this when i hit 100K and i picked up almost 2.5pmg!

A 2000 3.0 from a negligent owner ?
Get a camshaft syncronizer assembly from Ford (Get the Motorcraft brand only) and swap it out now.
They are a known failure part and if it goes bad you can/will lose your engine as it drives the oil pump.
DO NOT buy the cheap Dorman brand as they are known to fail in less that 20,000 miles.
Cost may be around $90.

Also, Thanks, I will look into that. But no Napa brand eh? Darn, I get a discount

Look in your owners service guide for the BIG service intervals 130K and perform that service yourself should be good to go

Carefull when cleaning the lower part of the throttle body.
What looks like black buidup may actually be a factory applied coating.Its there to protect the lower part of the bore.Don't scrub it off.

that link is what im referring too. I took it one step further an cut a second (2nd) identical hole on the same forward face of the box with a jigsaw. AND I drilled five (5) 1/2" holes in the bottom of the box to drop out sand/water/crud that may make its way into the box
