if it ain't broke...

i'm the original owner of an '02 overland w/ 150k miles. it's been serviced well enough throughout its lifetime as far as drivetrain lubricants and engine oil filters. i followed the schedule b program for the most part.
so now, it's a little long in the tooth and possibly/is needing some freshening up in other areas.
would it be worth the expense to replace the tps, o2 sensors, fuel filter, brake fluid, coolant, etc...you know, stuff that i've kinda neglected and/or has otherwise caused problems for other owners?
what might be some other components to consider???
i know it's mostly in the owner's manual maintenance schedule but, frankly, i've forgotten when i've done what, if ever.
having your thoughts on it could be helpful.
thanks.

Ya if it ain't broke don't fix it... but preventative maintenance goes a loooooong way If it's running rough or something a good many people have cleaned the gunk out of their throttle body, I've heard many good things about seafoam as well. Fuel filter and 02 sensors will give you WAYYY more MPG if they haven't been replaced in a long time, these are usually the big 2 that bring MPG down.

yeah, my mileage has sucked lately. i've never replaced the fuel filter or o2 sensors. i guess that's a good place to start.

Definitely do the fuel filter, I did mine yesterday and drove about 60 miles today just to test it out (who says its a waste ) I went from fighting tooth and nail to get 14.5 (I'm talking like 85% highway here) to about 17mpg with about 65/35 (highway and city respectively). I realize its a small data pool with only about 60 miles, but still, its gotta count for something with that kind of difference.

In short, fuel filter = godsend. Also it only cost me 21.65 or something along those lines from Summit (through Amazon).

I don't know how your winters are there, but road crews around here treat salt like its grass seed when it comes time for winter, so my fuel filter removal and installation was a bit more work than it should have been. Bolts locked solid with rust, one of the fittings solid rust, finally get bolts out after much PBBlaster soaking, they look more like nails, all threads are gone on both them and the holes in which they belong, etc etc and so forth. Long story short, it took me about 3-4 hours but that includes trying to clean up the rust having to find a bolt that would fit the now enlarged holes and fiddling with those fittings for 20-25 minutes a piece. Totally worth it IMO though, at least so far for me it's been great.

Consider a coolant and brake fluid flush to.
