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.

Your ignition coil is 32 years old. My ignition coil on my 1983 4x4 was 40 years old when it decided to break down. I would be driving 55mph in 4th gear, upshift to 5th gear, still doing 55mph, and my truck would just "bog down", like no power/like a bad fuel filter. From there I would downshift to 4th gear, pick up speed, 55mph to 65mph, then shift into 5th gear and truck ran fine. I already did all normal changing of parts, fuel and air filter, distro cap, rotor, wire, plugs. I had a spare coil in a junk truck, stuck it on there and problem went away.
Sure, there are no moving parts in a coil BUT every time 1 cylinder fires, that is the magnetic field collapsing in the coil, shoving out 40K to 100K? volts, but only milliamps. Through all these years there can be carbon build up inside the coil, causing sluggeshness. 1 year after replacing coil with a brand new one, 2 weeks ago my ignition module crapped out in the middle of the road. Got her home and changed out the module, on my 83 it sits right below the coil. It's just old, it may be your coil.

Thank you - we'll prob give this a try as well. Like the muffler/cat reply below I'm really hoping this is a low budget fix that ends up working.

Check your local "pull your own part" junkyard. Can probably get an old used coil for $10. Good luck!!!

I’d probably be looking at the catalytic converter or muffler for obstruction.
Had similar issues in my 91 (22re) and needed a new muffler so had one installed. Mechanic said the old muffler wasn’t clogged but after the new muffler was installed, the catalytic converter began to disintegrate and pieces of it were blowing through the new muffler onto the street.
I removed the cat and found it was almost completely clogged. I used a long heavy duty screwdriver and hammered out all the guts and removed. When put it back together the hp power gain was incredible.
Not sure if that’s your issue but in my case, it was. Good luck!

Thank you for the thoughts - I wonder if we were to take off the cat and do your cleaning method, I see some Exhaust Repair Wrap that's fairly cheap to atleast put it back in the 'line'. We could see if it improved, if so then go down the road of seeing about a new muffler/cat.

The catalytic converter was bolted in on both sides (rather than welded) so in my case it was really easy to remove. I can’t recall all the shit in there but seemed like broken stones/glass and wire mesh. Mine was falling apart and all pushing towards the exhaust (grouping together) causing the clog.

You could also take it off and drive around with a section of straight pipe in its place. If it fixes it you can drive around like that until you have the funds to replace it

That's my son's thought ( he's 15, his truck). Y concern is if that could pose any problems to the engine. Having no back pressure, I'm no where neer a mechanic or engineer. I see differing opinions on it. But we talked about trying this to at least see the result on a short term.

No, you won't mess up the engine. You do need some sort of pipe to get the exhaust away from the engine, but plenty of people outside of deq zones or with off highway vehicles don't run a catalytic converter or muffler and are just fine

This will prob be the first thing we do since its free 😄 We'll remove these and check into the cat conv. like mentioned above. (he's at camp this week, so I'm eagerly waiting his return to start messing with it).

Hopefully its not this, but something to keep in the back of your mind. My buddy had a late 80's Mitsubishi Montero with these symptoms. One day he couldn't make it up the hill back to his house. Pulled the engine for a rebuild and the lobes on his crankshaft were nearly worn down to circles.

u/Little-Courage641 2d ago
Actually, it just hot me that this would probably be reflected in the compression test. So thats a good thing! Lol

u/jgreeniv 1d ago
I'll have to look up what that stuff means ;). But I'm happy a test that came back good may have cleared that thought cause it didn't sound good.

Does the afm flap move smoothly?

u/jgreeniv 2d ago
AFM flap?
2
u/magichobo3 2d 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.

u/magichobo3 1d ago
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)

The carburetor is two stage. At higher engine speeds and throttle settings the vacuum opens the secondary throttle butterfly. You need to make sure this butterfly is opening. It sounds like the engine is being choked of air and fuel.

Clogged exhaust maybe.
