    Should I replace non-faulty fuel injectors?

    Thanks, Guys: I'm at 145K on the odometer and am thinking to send them in for cleaning per recommendations... Another quick question- Assuming the #6 is bad and I replace with a new one while cleaning the older ones. Does the new one need to be calibrated against the others older ones for...

    Should I replace non-faulty fuel injectors?

    Hi Team: So, I have been down a cylinder for a bit on my '93 FZJ80 and finally tracked it down to a toasted #6 fuel injector based on a resistance test. The other injectors' resistances are pretty close to spec. Is it recommended to replace all of the injectors at once or is it kosher to...

    Rough Idle No CEL Code

    Hi Team: I'm kind of a newb to working on rigs, so hoping for some guidance from the experts on what I should check on my '93 FZJ80. I'm experiencing a rough idle and rough engine under load. It also feels like I'm down a bit of power, but I can swear by that claim. I'm not throwing any CEL...

    Rough Engine no CEL codes

    Oh and PS- a week or so before the engine problems started, I did have a new to me torque converter installed as I somehow managed to break the input shaft on mine (still scratching head on that one).

    Rough Engine no CEL codes

    Hi Team: I've been battling this one for a while with no luck. I have a 93 FZJ80 that's experiencing a pretty rough idle and distinct engine vibrations at highway speeds. The CEL isn't on and no codes are being thrown after jumping the diagnostic terminal. It also feels like i'm down some...

    Help with Rough Engine Idle Triage

    Thanks, Inkpot. I've never done a compression check so sorry for the newb question. If a cylinder was losing pressure, would I feel the roughness throughout the ride vs just when in idle? Probably an obvious answer, but again- I'm a newb :) Thanks in advance

    Help with Rough Engine Idle Triage

    Hey Team: My '93 FZJ80 randomly started having a consistent rough idle when in Gear (including Reverse). I'm interested in thoughts on what else I should investigate. In park, I idle a little above 1K RPM and the engine runs smoothly. When I put her into gear, I kick down to about 700 RPM...

    Idle Air Controller (IAC) Valve Test failing

    Thanks, PPC- So is there actually no visual indication that it worked correctly? I thought the plunger was supposed to go in/out when open/closed. On mine the plunger doesn't seem to be moving at all. Thanks again!

    Idle Air Controller (IAC) Valve Test failing

    Hi Everyone: I'm having trouble with a rough idle when my '93 FZJ80 is in gear. I initially thought it was a bad IAC, so I pulled the sucker out (which is a massive pain) and tried testing the unit by hooking it up to my battery via alligator clips and following the FSM test guide. Low and...

    93 Transmission Rebuild or something else?

    Alrighty Friends: So I finally bit the bullet and took her into a trans shop. After dropping the trans, they're telling me the input shaft on the torque converter has sheared off in the engine pilot. (Or whatever the input shaft sticks into). As a result, I need a replacement Torque converter...

    93 Transmission Rebuild or something else?

    Hey Guys: Sorry for the confusion. It's a '93 FZJ80 so I'm pretty sure I'm working with the a442F. Not the a440.
