My 95 22re 4wd pickup.
Hey there. New guy here, new to the forum, new to Toyota's.
I recently purchased a 1995 Toyota pickup with 4wd & the 22re engine.
The day I bought it, I drove it thru the neighborhood, it ran with just a slight stumbling, nothing to serious.
It had a loose ps pulley which i fixed by tightening it.
It also had a no start issue where the problem was just corroded battery connections.
I changed the oil and filter, where I found out the oil drain threads were screwed up, and there was a weird plug that Ive never seen before keeping the oil in the pan. (Ive seen a lot of oil drain bolts in my time, haven't seen em all, but this was new to me). It was kinda like a drywall butterfly bolt/nut contraption. I wonder how previous owner installed that. Anyway i put a normal drain bolt in, its tight but leaks. Future repair will be to pull the pan and maybe diff (idk, new to Toyota trucks) and weld a new nut in there.
I also installed a small tachometer. I cant stand a vehicle with a manual transmission and no factory tachometer.
Anyway...
Sadly this is where it sits now:
The main issue now is/seems to be the knock sensor. That's what the trouble code tells me, it starts, idles fine, but giving it throttle results in hardly anything at all, bogging, stumbling, cant get it to rev.
So that's what I'm on now, trying to figure out where the knock sensor is, trying to figure out the wiring. The haynes manual isn't much help. Going to download the FSM tonight.
More to come.

It seems the last owner was getting the oil changed at the Quicky oil change and the screwed up the threads in the pan.
It seems the knock sensor pig tails go bad.
Remember the code is for that complete circuit not just the sensor !!!
the knock sensor is in front of the starter without looking I can`t say .

^ Yes, The top picture, thats the plug I have, lol.
Alright so further inspection i find that I don't have a knock sensor installed!
According to my research its suppose to be located left and a little above the oil filter, and to the right of the fuel filter.
I see the hole its suppose to thread into, but nothing there.
And there is no connector hanging down from the harness, although I did find a yellow wire w/green tracer hanging down with no connector.
Also, there is a sensor located right under the oil filter which I assume is the oil pressure sensor? There is a black wire going to that. Correct?
What to do?

Also, last night i downloaded a FSM from this thread:
https://www.yotatech.com/forums/f116...gation-288767/
But there seems to be no wiring diagram section, unless I looked in the wrong section?

So I think I fix the knock sensor issue, there's no more trouble code, and the truck runs a little better? I guess not. lol.
So it still runs crappy.
I checked the plugs, they look fairly new, I cleaned them off, checked the gap, reinstalled them.
All the wires are going to the right places.
I'm currently in the middle of checking the timing.
I seems way off, I twist the distributor in all directions which doesn't seem to make much difference, if anything makes it worse.
I'm beginning to realize why this truck was sold, gremlins.
Funny it runs worse now than the day i bought it.

there are a lot of things that could be bad, but you'll need to troubleshoot things by testing. it will get very expensive to just throw parts at it without verifying the parts need replacement. don't do that.
it will be cheaper in the long run to invest in a few tools that will help in diagnosing problems. first and foremost is a decent multimeter to test wiring. fuel pressure in these is also important - it should be up around 30 psi. they will run at lower psi, but will run terribly and inconsistently. get a fuel pressure tester, or install a fuel pressure gauge. obtaining the meter and a pressure tester (or gauge) should run you less than $100 total. it will cost much more than that to buy a fuel pump, afm, injectors, cap/rotor, ignitor, TPS, etc. that don't need replacing.
