    Intermittent signal loss from all four 02 sensors

    Been chasing down a running rich issue for a while now and I made a scary breakthrough tonight. All four O2 sensors are randomly and simultaneously flatlining. When it’s running normal, upstream sensors will oscillate between 0.1 and 0.7 ish volts and the downstream sensors will hold relatively...

    Help: LR brake rubs when turning right

    This only started after installing new rotors and pads. Title says it all: Left rear rotor rubs only when turning right. I can’t tell WHAT it’s rubbing on though. I’ve bent the dust shield way back, removed and inspected the caliper, gave the wheel bearing the wiggle check, torqued wheel to...

    A doozy: 2UZ transmission going haywire... Until scan tool plugged in.

    This is on my parents' 1999 Land Cruiser, 4.7L 2UZ, A340F 4-speed auto box. When starting out, it shifts roughly into drive, and feels jerky and sluggish getting up to speed. It won't upshift past second, and won't engine brake when the gas is released. Then, when coming to a stop, it'll stall...

    Momentary crappy idle on cold start?

    1998 GS400, 206k miles. When I start my car first thing in the morning, it'll fire up right away, settle at 1200rpm for a second, then slowly dip to around 1000-900 and stay there for about five seconds before returning to 1200. Every so often, usually when it's colder, it'll start up and then...

    Need trans help: bad clutch, leaky solenoid, or pressure too low?

    1998 GS400, 205K miles, original drivetrain. No trouble codes. Trans fluid was pretty dark when I bought it, so I flushed it all out through the cooler lines. I also dropped the pan and turned the pressure dial to max. So I’m still trying to figure out why my 1-2 upshift and 2-1 downshift are...

    A650e feels very weak

    1998 GS400. Even with the pressure dial all the way up, I can barely feel the gear changes at any level of throttle. I drove two other GS4s which likely didn’t have the pressure dial turned up, and they change gears much more solidly. My fluid is all fresh, but when I first had the car is...

    Are all V8 A650E transmissions the same?

    I've searched, and so far I've come up with the following conclusions: The A650e from the GS400 has a different valve body tune than the one in the 300 to manage the extra power. The 400 A650e will work fine in a 300, but the opposite may not be true. The shift position sensor is specific to...

    2UZ plastic intake successfully installed on GS400

    So my ACIS solenoid died, and the intake manifold had to come off... So I figured, why not buy the plastic 2UZ intake from badblackgs and see what happens when I install it? From his experiments with it, he noticed a decent increase in torque. Plus the plastic keeps the air temperature down and...

    2005+ 2UZ plastic intake manifold

    Like the title says, I have the black plastic intake manifold for all 2005 and up 2UZ engines. It will also bolt right on to the 3UZ, and I have injectors that are plug and play with the 2000-2002 3UZ harness. To make it work on a 3UZ the holes on the throttle body just have to be filed out a...

    2UZ plastic intake on 1UZ-VVTi

    I found one post on ClubLexus about fitting a 2005+ 2UZ manifold on a 3UZ, which means it'll fit a 1998+ 1UZ. There are other posts that say this topic has been covered here, but I can't get search to work. Has anyone done it? How bad is the job? The CL member said he definitely felt some...

    2UZ revs quicker than 1UZ?

    Here's one from my "inquisitive child" mind. My mom and my uncle both own Land Cruisers, 98 and 00 respectively. Their engines are much more nimble on the tachometer than my 98 1UZ. In neutral, the 2UZ jumps to 3000rpm almost twice as quick as my 1UZ. Obviously there's no performance impact...

    1UZ VVTi/2UZ non-VVTi alternators interchangeable?

    The alternators of the 1UZ/2UZ from 1998-2000 look almost identical. I was researching into this a while back, and someone mentioned the only real difference is an extra mounting tab on the 2UZ alt that can be ground off. The plugs are the same shape. Can anyone confirm if the mounting tabs...

    My power curve ain't right ('98 1UZ VVTi)

    This happens under anything less than full throttle. As the revs build, right at 3700rpm WHAM there's a sudden jump in power. It's a noticeable push back in the seat. I assume this is the ACIS switching to short runner intake mode. The engine seems to be running fine, but I don't think this is...

    Max efficiency at 2500rpm?

    If my experience on a mountain bike is any help, I believe the 1UZ has a sweet spot: When biking, if I can get my pedaling speed at just the right spot, the natural inertia of my legs does most of the work. I've noticed on the freeway, if I have the cruise set at 75mph which equates to...

    Wanted: Gold passenger front fender for 2GS

    Hope it's ok to ask for body panels on this forum. Car was hit. Fender is the only damage. Need a gold front US passenger side fender for GS300/400/430, paint code 4p2 "burnished gold metallic." Willing to pay shipping. Let me know what's available.

    ECU interchangeability?

    Planning a manual trans swap on my GS400. The ECU will obviously need to be dealt with. I'd prefer to keep things as plug-n-play as possible, and one of the questions that I haven't found an answer to is this: Will the Crown Majesta ECUs swap straight across with the GS400 ECU, or are the...

    Is this the definitive A650e manual swap wiring solution?

    Ok. This thread popped up on ClubLexus. Credit to maxEX84. It appears to deal with the subject of tricking the ECU to think everything is OK when doing an A650e-to-manual swap. The wiring issue was one of the biggest things I needed to see a solution for before I considered a manual swap. I...
