"We never did figure that out"
This is the quote I got from two 15 year Toyota technicians when I asked what my underpowered/missing issue could be. On cooler mornings, it will be underpowered - smooth operating, but like half the HP. Not constantly, but for a few seconds at a time. Then once I get on the highway, it's a long uphill, and it will miss randomly a few times, then it's fine (for a 22RE with 206k). When I asked these guys about it, they said that they have seen it before, but never figured out what it was. They have some ideas, but they range all over the map. Do any of you 22RE owners have more concise ideas?

I had a bad EGR valve cause this on my 3slow. I discovered this on a fluke messing around under the hood. This was after the goofball dealership had their super diagnostic guy tell me the injectors were going bad and leaking extra fuel in the engine. I changed the injectors myself and it did nothing to help. Won't be going back to Keyes Toyota, Van Nuys anytime soon.

check the cap & rotor. After market cap & rotor kits are terrible for this kind of thing. If it looks a little scored replace it. I had the same proble on my T4R, tried everything, took it into the dealer thinking maybe coil, turned out cap & rotor (only 6 mo old) boy I felt dumb, at least they didn't charge me the diagnostics

So your saying that it misses under load when cold? True?
It is hard to say since it only does it once in awhile, not constant, could be dirty injector - Under load forcing more fuel pressure along with dirt, more common when your fuel tank is empty sucking the bottom for dirt!
I probably didn't help you either, "a" for effort!

Good suggestions, most are precisely what the Toyoa techs suggested. I'm going into the shop tomorrow to put my new muffler on, so perhaps I'll check these systems while I'm there, and I should be able to get asistance from one of the techs I mentioned...

this prolly isn't it, but something to check if nothing else turns out to be it...
small crack in the head.
i've read about a few cases where 22REs had small cracks in the head...they would run fine when hot because, as the head expanded, the crack sealed itself.

first of all, that makes no sense that the pickup would be at the top of the tank hhahahaha shame on those people
but seriously, if a tank runs dry cant it mess up the fuel pump? or is this a myth as well
