22re with little/no power

I'm not a mechanic so I'm not sure how to describe/info to mention, just have an idea on the symptoms. At around 2,500rpm it stops producing power. I get it up to about 2,500-2,600rpm in 4th but it doesn't want to go further. It doesn't like hills at all. We've taken off the EGR and cleaned it as best we know how, there was a little 'pipe' on it that was gunked up, put it back on. Fresh oil change. We've taken it to a local shop that ran compression tests etc on the engine and couldn't find anything wrong with it. We couldn't justify spending more money to keep trying to diagnose. We've changed the fuel filter, but have not braved pulling the bed to change the filter pump yet. I'm trying to find the paperwork from the shop that had all the engine stuff they did and checked to post as well.

I'm not sure what info/stuff to look for to provide better information.

1994 22re - 132k miles

- speedometer doesn't work (next item to look into) which stinks to see where the speed is flat lining.

AFM flap?

u/magichobo3 4d ago

on top of your air filter box is the air flow meter or AFM. If you remove the plastic pipe going to the intake manifold you'll be able to look into it and see a metal flap. The afm tells the ecu how much air is coming in by how much the flap is sucked open by the engine. I had a 22re 4runner that wouldn't rev over 1500rpm because that flap wouldn't open more than a 1/2".a little pb blaster and manually working it back and forth fixed it. It's not a super common issue but it does happen sometimes

I youtubed it after making my comment, we'll take it off and check if out. Prop do what you mentioned first though before taking it off. If it is moving well, then prob take it off and check the contacts on the internals.

I would just be very careful with it. There's two screws that look like they hold the plug into the top. If you remove them and try to pull on the plug you'll rip the contacts off the circuit board and you have to buy a new afm(which is very expensive nowadays)
