No engine stated, but you did hit most parts, unlike most post here.

does the check engine glow when the engine misfires.????
that is misfire, (shudder)!
ever give it a real 60,000 mile interval tune up, by the book, yet?
that is what it is misfiring or bogging, bogging is just extreme misfire.
its intermittent ,which means the shop wont find it. (most likely).
what i do is connect my scan tool and log all the major PIDs and DTCs. to file. then when it messes up.
i go home and play back my log file.
bam there it is. Clear as mud. right..
Im going to assume this is engine problem and not tranny slip.
STALL word, key.:
this is where OBD2 excels, finding determinants.
and nobody seems to use it.
here are some examples. (in each case , so can it be wires and connections, no need to repeat that mantra.
1: lost comms. the ECU just lost 12vDC power, (fuse and power feed issues, (more test to do , ask how)
2: MAF dropped to zero air flow (gee its bad or the wires to it are bad)
3: ECT dropped out , ditto
4: IAC, dropped out , or TPS went nuts.
5: you were cruise 40mph and the 02 front sensor when ape sh't
6: at cruise. and P0301 hammered the memory. injector 1 wire loose.
301, spark plug 1 , cracked insulator.
301, intake valve 1 , stuck. (more freq, oil changes are needed.
7: P0300s, the fuel pump (or friends) decided to go to 10 psi, for kicks and giggles. or lean DTC codes.
log the DTCs driving,
and look for pending fails.
the logging of sensors give you a signature of the failure.
its a very powerful tool. that few dealers use. (right)

sorry you have intermittent. the internet bleeds with them.
they are for sure very hard to find , blind. (pre 96 cars are mostly blind)

for DC power problems, i use my logging voltmeter.
and win. every time !
if not , out comes my logging DSO..... but only rarely....above gets 99%

You have water in something You will have to dry it out especialy the wire joiner plugs.Could have also inadvertantly shown up a coil problem.The coils get cracked from the heat of both engine and itself operating.When you pour water around the base it gets into the coil and plays merry hell.

Hi, the problem you are having sounds like the differential needs replacing this can be expensive and hard work but not doing this can cause further damage to your vehicle so its better get it done sooner rather than later.
If on the other hand your only getting a vibration through the steering wheel then this could be that the wheels need balancing.
You should know which of the two problems you have if you need further assistance then just let me know ok

SOURCE: after 45 minutes of driving my transmission changes rough

These transmissions were known for having PCS(Pressure Control Solenoid) problems with the higher miles I would agree on a complete trans flush and filter change.The Pressure control solenoid sarts to hangup causing high pressure when not commanded which will cause hard shifts.

1997 4Runner 4wd, 6cyl Limited. Engine running rough. replaced plugs, wires, coils, fuel filter, and computer and still runs rough. I discovered codes on invoice of P0300 and P304. Have paid a lot of $$...

could have a dirty fuel injector, ad some cleaner to a half tank of fuel, you could have water in the tank and many other things. Are you getting any service lights? Does it run rough all the time or only on rainy days? p0300 and p0304 are both misfire codes, i would try cleaning the fuel injectors first.

I don't have good news for you.
If you have an automatic tranny on your 4WD this is prohibited, per Toyota. It's your transmission that's probably making the noise. It's lubricated when the engine runs and the transmission pump is circulating oil through the system. During towing, when your drive wheels were spinning with the engine off, no fluid was being pumped through the system. Friction, etc. can quickly wear down bearings and seals, etc.

If this was towed professionally they should have known better... You might have a case due to professional negligence.

Hope this helps, but sorry.

A/C quits after about 30 to 40 minutes of runtime on my 1995 Toyota 4Runner A/T 4WD Limited. Will run okay again after it's turned off for about 30 to 40 minutes, even on the highway. There is no power...

I had a Live Chat with u, we were disconnected, your problem is most likely the AC expansion valve, this part is located in the low side AC line just before the evaporator core in the dash., u must evacuate the system to replace the part and then pull a vacuum (with AC vacuum pump) and recharge the system..

Rough running 86 4runner after e85 put in!

very likely the fuel injectors are damaged, replace them, the fuel pressure regulator and all rubber fuel lines, also pull the gas tank and replace the short rubber hose at the electric fuel pump, I know this is expensive but even a few miles of running would have wrecked havoc on the rubber components, that rubber debris will flow through the fuel system and will plug the injector's, E85 melts it and skin for that matter.
