I just bought a 92 4 runner 3zve automatic. When the car is cold and i accelerate it runs fine to about 4000rpm then kinda barley osculates between power and no power(feels like the throttle is moving back and forth very very lightly). When the car heats up a little it will cut completely for two seconds, if I keep my foot it the same spot it dies out then it accelerate, then die out then it accelerates(it won't stop until I let up). I'm pulling out my hair over this. The check engine light came on do to the tps so I replaced and readjust it with the running method. The truck has new fuel pump, filter, injectors, plugs, wires, o2 sensor. I just can't figure it out

Hey Conman 77 - I, too, started a new thread yesterday as I'm having the exact same problem with my 1993 4Runner that you're having with your 1992. I had searched this site for weeks looking for a fix...never found one. Hoping that someone can help us both out!!

 

No other error codes? if the knock sensor is error coding you'll most likely have similar to exact effects of what your running into. I replaced the wire harness to my knock sensor while in doing my timing belt. other wise if no trouble code hard to say whats wrong unless something is just not adjusted right or vacuum hoses wrong

 

Now it cuts out and pops through the intake, fuel pump? Coil? Valve lash? I'm pulling out my hair

 

possible to post a video of what is happening?
When i did my timing belt recently, the bits of coolant that made it into the valves, burnt away when i started it up for the first time, if was very sputtery, and scary to see, thought it was the end of her, but then it burnt it all off, i would guess if you have An internal coolant leek somewhere, maybe a hg? But don't take my word for it. It would have a similar effect, the exhaust would also be very white smoky if so. I my self also have a coolant leak, rare in my case, an external blown hg, coolant was poring out externally, i put A bottle of kseal in the coolant and fixed her right up.
