    Real-time Christmas help needed: second alternator died in two months, keep blowing diodes

    Two months ago the alternator in my parents’ 1999 started making a weird whirring/moaning noise, and about two days later stopped charging. Replaced it with a reman unit from my local dealer. This week that unit started making the exact same noise. It’s still charging at the moment but the...

    Bouncy Bilsteins?

    So lately my mom says her 1999 is way bouncier than it used to be. They got Bilsteins installed in it in June (not sure exactly which ones) and it already has a torsion bar crank + rear spring lift and 33-34” tires. She says it started just a few weeks ago, and it does seem to get rather bouncy...

    Alternator rebuild kit source? Unsure of what's trustworthy

    Mom's 1999 was making a funny moaning noise yesterday, so I went and took a look. Definitely alternator side of the engine. With my stethoscope I couldn't hear it through the power steering pump, could kind of hear it through the tensioner, but I couldn't get the scope onto the alternator to...

    Trying to find part number for the keyless beeper

    So Google has gotten "so smart" that when I try and find the keyless beeper for a GX470 it keeps giving me results for remote starts, key fobs, key programming, etc. because it thinks that's what I mean. I actually want the part number for the "beep beep" module that sounds when unlocking...

    Bleeding just the accumulator on the brake booster?

    Replaced the brake booster on my parents' 1999. Found a used part. Install went fine, line bleed went fine. Nothing leaks. However, about once a week the ABS light will stay on for an additional 10-20 seconds after the vehicle is started. This seems to indicate the system losing excess pressure...

    Brake boosters for 99 LC… can’t get?

    Mom’s 99 is in need of a new booster assembly. It’s still working, but it leaks, and with 270k on the truck it could lose a motor or a seal any day now. I want to replace the entire thing voluntarily before somebody’s day gets ruined. There’s absolutely nothing on eBay other than non-brand...

    How to fix a dodgy MAF plug?

    Short version: I suspect my MAF plug isn't making good contact. How can I either add strength to the contacts, clean them real good or maybe put something in them to help with electrical flow? Long version: That rich fuel trim problem I've been dealing with is still happening, but I think I've...

    More evidence that fuses are wear items

    When you buy an LC and baseline everything, do you change the fuses as well? I certainly didn't when I bought my 1UZ-powered GS400... I've owned it for four years now, and it's always had a sloppy 1-2 gear change. I chalked it up to abuse from the bozos that owned it before me. Last year it...

    Buttload of warning lights but nothing is actually malfunctioning - ZPC??

    Posting in behalf of my uncle. He just got a 2008 GX470 in pristine condition with 80k miles on it. He replaced the shocks, springs and tires for a 2" lift and eliminated the electrically-controlled shocks. He did not do a zero-point calibration on it after the suspension work. Two weeks later...

    I suspect Walmart gas is crap and UZ motors don't like it

    Being a poor college student I opted for Walmart gas in my 1UZ (with 2UZ intake/injector mod) almost exclusively for the past two years. Also for the past year it just hasn't felt entirely healthy, and lately I've been chasing a rich fuel mixture problem. I suspect sticky injectors because it...

    RTH: Temp gauge and transmission having psychotic episodes

    UPDATE UPDATE UPDATE: With a scan tool plugged in, the issue disappears and the car runs perfect! I can unplug the scan tool mid-drive and it’ll go back to crap. Mom called me a few weeks ago complaining of stalling and generally weird running. Had to park the 100 because it was getting worse...

    Another remote diagnostic situation: Funny shifts=bad MAF?

    Yeah, so I'm still in Idaho and my mom's 1999 is acting up in Utah. She called me a few days ago saying the transmission was downshifting rough, and it generally felt sluggish. Early today she said it jumped gears in a funny way when she floored it to merge (not slipping), and then just barely...

    RE-SOLVED: Engine running way rich, 0V reading from all O2 sensors - BAD FUSE

    This is for my Lexus but the motor is basically the same so I’m imploring you knowledgeable MUD guys for help on this one. I used to have a bunch of vacuum leaks (positive fuel trim). I fixed all of those and the engine was happy for a few months with fuel trims sitting perfectly at 0 give or...

    RTH: Oil sprayed everywhere, bank 1 now misfiring

    This is a follow up to my other thread. I drove to Utah to look at the Cruiser. After the oil sprayed out of the filter housing area, the shop cleaned it up and refilled it. My mom took it home so now I have full access. It fires right up and sounds completely normal. No knocking at all, even...

    RTH: Motor ruined, need replacement! 1999

    Sudden oil loss killed my parents' 1999 motor today. Barfed oil all under the driver's side, lost all oil pressure and then quit running. They just had the oil changed, and the shop that did the work is offering to eat the cost of a new motor. They're in Utah, and I'm in Idaho playing...

    Impending rear third member swap - arm me with knowledge

    Sister is currently driving the FJ80 (heaven help us all). She's been complaining of jerking and hesitation as of late, and the shop that we find quite trustworthy says it's the rear differential. I'll be in town to deal with it next weekend. I installed a Spartan locker myself back there five...

    Charcoal canister purge and cold engine?

    The charcoal canister on the 100 starts putting off some nasty smells after driving at high rpms for a while (climbing hills, highway cruising, etc). The VSVs both respond when tested with techstream. I know it’s possible that the VSVs fail when hot, and seem normal when tested cold. I have...

    Part number request

    For the 1999. Replacing both of the solenoids that control the charcoal canister. I found the one that bolts onto the intake but I'm having a real hard time with the one on the canister itself. Circled below. If anyone knows what the part number is, can you help me out? Thanks in advance.

    Lexus GS alternator swap mod?

    So I had the alternator out of my 1998 GS400 the other day, and I compared it to the alternator I took out of our 1999 LC. They look identical. Rear plugs are the same shape. The GS alternator is 100-amp. The LC alternator is 80-amp if I remember right. The only thing I don’t know is the...

    Why is my fuel economy all over the place?

    1998 Lexus GS400, 4.0L 1UZFE V8. Runs like a top at 206k miles. I routinely make trips from Idaho to Utah and use the time to check MPG and engine performance and such. -Last weekend I got 26mpg with the cruise set at 80mph. Weather was good, in the 40s and dry. No headwind. -Same trip today...
