Hey all, picked up a 1985 4Runner SR5 (manual, 22RE). It had a refurbished 22RE motor swapped in, but the truck has been missing since I got it. I have been trying to track down the issue, and haven't had any luck yet. I've been scouring the forums looking for things to check.

Issues: Missing, CEL - Knock, Hesitation/Stutter ~1800-2400 RPM

So far I've checked/verified/replaced/done the following:
- AFM - Checked, was bad and replaced.
- TPS - Checked and adjusted to in spec
- Wires, Plugs, Distributor Replaced (When I replced the distributor I set to 5 degrees BTDC)
- Pulled the Throttle Body and Upper Intake Manifold and cleaned them
- Pulled the valve cover and adjusted the valves. [While I had it at TDC (0 degrees) the holes on the gear were at 12 o'clock]
- Checked the timing, it bounces around a bit but seems to be staying with 5-8 degrees at idle
- Adjusted idle to ~700RPM
- Replaced the vacuum hoses (I still think there might be a leak, but I can't pinpoint it.)
- Checked the injectors, all reading 2.5 OHMs, also listened to them and they are all ticking like I'd expect
- Compression Test shows 161-165 psi on all 4 cylinders (warm).
- Fuel pressure test comes in at 30psi regulated when idling.

I think at this point all I have left is to look into fuel and electrical issues. Is there anywhere else I should possibly look before I go down that route?

Any advice on which direction I should go and advice on order I should approach things?

Would I be correct in assuming the item circled in red should be my knock sensor and the PO just plugged it?

Sounds like maybe a timing issue? Detonation?

gixxsta04 you're digging up some pretty old threads to stack your post count.

To the OP looks like your knock sensor is broken, hopefully you found a fix for all of this, we'd love to hear what it was.
