I bought a 9,000 lb car lift last summer from an estate sale just down the road from me, and it's a joy to work on my vehicles now.

Damned O2 sensors.... my '04 Suburban has a total of four, two on each side of the exhaust system, one pre-cat and one post-cat. It started to throw a code and it was the #1 O2 (driver side pre-cat), but IMHO if you need to replace one, do them all so they're all the same "vintage". Not the most accessible components to get to w/o a car-lift!

speaking of 04 burbys, in my opinion it doesnt get much better than 96-early 2007 GM gasoline trucks.

I had a '99 that got better fuel @ 18-22(ish)mpg, the '04 averages 14-16mpg... go figure.
