    Not-quite-RTH: Good downstream O2 sensor readings? '96 FZJ80

    I'm having a heck of a time troubleshooting an issue keeping my 96 FZJ80 from passing smog, and I'm hoping the braintrust on Mud can help me out with some diagnostic data. Does anyone have a graph showing good downstream O2 sensor data (at temp), preferably both idle and up in the 2k+ rpm...

    Code 28 issues

    My 94 cruiser was intermittently throwing code 28 for a heated o2sensor for cylinders 4-6. I would usually pull the EFI fuse and the code would clear for a while but I eventually decided to replace the o2sensor. I ordered the NTK part #244044 which is supposably the OE sensor for the 93-94's...

    Replaced Bank 1 sensor 1 O2 heater but CEL still on.

    Hi all, Backstory: I recently purchased a 2000 with ~200k mileage here in New England. Windshield leaks (getting replaced this week, bad install), CEL on and throwing P0135 (Bank 1 Sensor 1 O2) But other than that, minimal rust on frame and beautiful body (was garaged most it's life) I...

    Smog delete?

    I have a 1994 FZJ80 with the 1fz-fe. Looking in to a smog delete including egr, o2 sensor, etc. Cats are already removed. What all would I need to do these mods? Possible issues I could run in to? Related threads? How difficult would this be for the average guy?

    2001 Corolla stalling, hesitation

    Just gonna post this up here, so maybe i can find it again later. This is a software problem, a firmware update could fix, but they will not roll it out. This throws O2 sensor codes, and then cyl codes as vehicle starts to misfire. Simple fix is to disconnect both O2 sensors in front of cat...

    Cleaning O2 Sensors

    I just replaced three O2 sensors on my 99 LC with 164k miles. The other was replaced at 121k. Since these weren't malfunctioning when I replaced them I thought to keep one of each for spares. I found a website that says to clean these just soak the sensor part, not electrical contacts, in a cup...

    Misfire 2UZ @3000rpm Fix

    Yesterday, one of our 100s suffered a misfire at 3000, wouldn't pull above that and ran slightly rough once falling back to idle. Did air/fuel filters, throttle body, air flow sensor etc. No joy. Seems an impact dislodged the LH O2 Sensor lume and it suffered heat damage on the Cat pipe. As a...

    Less power after new exhaust..?

    First off, this is my first post but ‘Mud has been a massive resource for me these last few months. In the last year I acquired a 92 FJ80 and since I’ve slowly been building him (“Lando”) up. So far: water pump, belts, hoses, power steering pump/pulley, PCV/grommet, tires/wheels (Duratrac...

    O2 Sensor options.

    I tried doing a search and most of them on this topic are really old. I have a '94 that needs a new No.2 O2 sensor. I just got back from my dealer that quoted me almost $300 for one, even at their wholesale pricing. I am normally a big fan of OEM, but that is just too much for my wallet at the...

    Ideas on how to attach O2 sensor to new exhaust pipe?

    Hey folks, My 97 fzj80 is at an indy exhaust shop today getting the over-the-frame exhaust job done. I went with the Magnaflow 23120 cat and a magnaflow muffler; going to see if I can reuse the tailpipe for now. Anyhow, the cat has one slot for the oem O2 sensor but, since I'm going down to 1...
