    FJ80 Transmission and Power steering

    Thanks! A foolish question for sure, but I recalled reading something way back that they were linked. This settles it in my mind, so I really appreciate the help.

    FJ80 Transmission and Power steering

    A few reasons for this question- I have an ATF fluid leak, but can't tell if it's power steering or transmission cooler hose. I also want to top off the transmission fluid. I installed a new radiator a few weeks ago and lost maybe a cup of fluid when I pulled the cooler hose off. As far as I...

    Does the FJ80 (91/92) have the power steering and transmission sharing the same reservoir?

    1991 FJ80 Overheated, no start

    What if the compression test is bad? I'm going to be doing it in a few days. Does that just mean full engine rebuild?

    1991 FJ80 Overheated, no start

    Sweet, thanks for the guide! I'd love to do an LS swap, but I'm not sure I have the garage for that. But buying another 3FE donor...that solution could work for me

    8x Series V8 Swaps

    Hey, sorry to be that guy...I want to see if or how a 5.3L Vortec can mate up with a A440F from a 1991 FJ80. Can any of you guys help me out? I'm having a hard time finding the info in the forum search. Please help guide me to the way, you Knower of Cruisers.

    1991 FJ80 Overheated, no start

    FJ80 overheated on the highway. Temp gauge shot up, white smoke everywhere out of the engine compartment, check engine light came on all in the span of a few seconds. Pulled over, coolant everywhere. Let it all cool off, kept the fan going to dump heat. Went to top off the radiator after...

    1991 FJ80 disable automatic door unlocking

    Doors lock on Start up need code to disable - https://forum.ih8mud.com/threads/doors-lock-on-start-up-need-code-to-disable.539196/ seems to work for later models. Has anyone tried to disable automatic door locking/unlocking on a 1991? I've tried the code with no success. My issue is that all...

    Accelerating troubles on 3FE

    Good point, it wasn't really clear. I tested the TPS and it showed as bad based off the FSM. I was worried there was going to be something else after I replaced, but it looks like everything's back to normal.

    Yeah, I was able to get OEM thankfully so it is still available.

    Accelerating troubles on 3FE

    Ongoing in this, the PCV and hose were swapped out and a 93 Camry Mass Airflow sensor were installed. Things are getting better, but now I've got codes 41 and 42, and still have the acceleration problem. Code 41 I get- the next item on the list is the Throttle Position Sensor, probably going to...

    The Ultimate 80 Series Parts Discontinued Thread

    I hate myself for doing this, but I really can't find the info in the search anywhere. The 3FE rear PCV hose is apparently discontinued. Is there a go-to part, or is this a fairly new issue? If you can find this by searching, could you tell me what you put in? The search and my Canadian accent...

    No drive without CDL engaged

    When this happened to me [1991 FJ80] (no drive except 4 low or CDL engaged) it wound up being that the drive flange was stripped and had to be replaced. It wound up being a full front end rebuild. It wasn't fun, or cheap, but it was still worthwhile; I wouldn't have redone the full front end...

    Accelerating troubles on 3FE

    Fuel filter went in today. Didn't really make any difference, where the charcoal canister definitely did. Still glad I did it, but it was not the problem. I did notice, though, there are small holes in the rusting exhaust pipe right below the O2 sensors- not obvious, but careful examination...

    Accelerating troubles on 3FE

    Update: AC Delco 215-153 vapor canister arrived and installed today. Before that I ran the truck for about a week without the canister, based off the 60 series forum 3FE info, and the problem definitely got better, but not completely gone: smooth acceleration was great even on long trips, but...

    Accelerating troubles on 3FE

    Thank you very much Jon. I did the fuel pump recently and put a new sock on and it didn't fix the issue. Faulty charcoal canister, though, is one that I really want to fix and has been a known issue due to vacccum whooshing at the tank. Getting a replacement canister in Canada has been a...

    Accelerating troubles on 3FE

    Do you have an intact EGR system? I have desmogged, it's hard to say if this is a factor. This thread 3FE- Loss of power/mild stumbling/at mid RPM range (Fixed it Thread) Whew. seems sort of similar to the issue, and it was desmogged. For this guy, it was a combo TPS/O2 sensor issue. Could an...

    Accelerating troubles on 3FE

    Feels like it is mostly load dependent. It has everything to do with how hard I'm asking the machine to accelerate based off how much gas I'm giving it.
