I had the O2 sensors changed recently. It may be my imagination but my F150 seems to have more pep. Could anyone tell me if this is a possible result or is it wishfull thinking? The truck is a 2001 F150 with 91,000 miles.

 

Sure, it's very possible. As O2's get old, they can become sluggish to reacting to changes in the exhaust stream.

 

i might have to change mine then. 180k on the originals

 

If you do, you only need to change the fronts. The rears do not affect the way it runs at all, all they do is monitor catalyst efficiency and trip a CEL when the cats are shot.

 

Did you change them yourself or did someone else do the work? I'm curious to know if this is something I can do.

 

i think theres a how to in the how to section on changing o2 sensors if im not mistaken. i belive i need to be doing the same thing along with a long list of tune up items

 

There is an excellent writeup around here - I think it's in the technical articles forum. The driver's side is pretty easy to get to from underneath once the truck is jacked up. The passenger side can be accessed from the fenderwell after removing the tire, skirt and the transmission dipstick. You will need an O2 wrench, which is just a crowfoot socket with a slot cut in it for wire harness. You can find it at any auto parts store for about 10 bucks.
Search for the writeup - it is very detailed with pictures.
