Drove home today and when I went to shut off the truck I noticed this after a small Rev of the engine.

Another vote for clogged cats.

You can just disconnect the O2 sensor before the cat and zip tie it out of the way. This will allow the exhaust gases to easily escape, take it for a test drive and see if your power is restored. If it is, buy a new cat, if it isn't, your cat is not clogged.

Don't drive long like this just do the test and see if the cat is the problem. Then screw back in the 02 sensor.

This is how I diagnosed my clogged cat with my grand prix and it worked perfectly. Once I put the new cat in, it was like driving a new car. They don't clog over night so if your truck has been sluggish for awhile now, it could very well be the cat.

Good luck

Did you take a look and see if you plugged back everything ??? Look thoroughly since some plugs can be well hidden on the back of the intake, or the MAF plug just back of the airbox.

UPDATE:

I went to the auto shop at the school that I teach at and I had some Diagnostics done and the teacher said that I should change the fuel filter which I did and then if that didn't change anything unplug the mass air flow sensor and see how well it ran. Will it ran crappie.
I have yet to do anything to the cats or the O2 sensors but I was getting p0420 code, said it was lean, and had maf code. I am unsure of the exact numbers of those codes. When I call the Toyota dealership and talk with them they make it sound like it has nothing to do with the cats.

Could it be the fuel injectors or could it be a bad transmission, or is the motor getting so old that with new tires and a lift that's its not going to go much over 70?

Another thought, I had the deck plate modified air box, should I do the same to the new Volant air box I purchased, maybe it's starved or air from the norm?

You need to fix the codes. Then move on from there.
