So in the attached image you can see the list of dtcs I have on a 2000 rx 300 AWD
I have tested coils and replaced spark plugs on 2-4-6, all should be in perfect shape.
I have tested unplugging the coils I could easily access with the entire intake assembled, which seemed to not affect the idle, leading me to believe that perhaps those spark plugs in the back are no good.
I am going to head back out now to work on getting to and replacing the 1-3-5 spark plugs, if I can manage.
1. With the intake and throttle body(s?) removed, is it worth any attempt to remove the o2 sensor from above? I tried from below several times, with PB blaster let to sit overnight, to no avail.
2. As I was taking off the intake filter lid, I could swear that one of the two "vacuum" hoses directly behind it, may have been unattached. I followed the one that is attached and it seems to lead to the Fuel Injector rail for 2-4-6. With this logic, would it make sense that the other tube leads to 1-3-5 injectors, and all this could have been from the vacuum leak causing those cylinders to run lean/misfire?
3. Is there anything else I should check while I have the throttle body's off (and cleaned up beautifully) like the MAF, etc? I do have a multimeter, but I have only tried using it a couple of times and am not 100% on which items to check for which values.
4. Is there anyone here with any insight on what values to check on my Code Scanner's "Live Data"? I found a great OBD2 scanner, but I don't know how to use these tools to verify the fix...
My plan now is to replace the 1-3-5 spark plugs, reassemple the intake, verifying all connections are made and see how she runs... but I will work at the o2 sensor or anything else possible, while it's apart.
Thank you if you read this! I am new to the forum, as I just purchased this car for my wife, so thanks in advance, if anyone hears this!
Reading the Wiki, and looking at CarComplaints.com and Edmunds, KBB, Cars.com reading extensively on owner experiences with the 09 and earlier LS460 it seems the smarter move is to buy the 2010-2012 iteration. Is that true? The changes seemed more than mere cosmetic with the 2010 refresh - paint changed, electronics [some], lighting, etc.
And are the notorious "control arm" bushings, parts, etc still in play from 2010 ownward? I do not want to be chasing driveability issues ad infinitum....
your wisdom is greatly appreciated!
Have an GX470 that has been a trusted companion for 8 years with 190k. Has worked for my wife and three kids. Was hoping to get the last 18 months of use until my last kid went to college, but the rear air suspension system is totally gone and the dealer quoted me $5,200. Dealer came back and offered a “kit” that would convert to a standard suspension that would be $2,200, but the car still has another $2-3k of other repairs to get it back to “normal”. I put Almost $1,500 into the air conditioning system a few years ago and promised that would be the last major investment. I was surprised that the blue book value still says the car is work $10k. Should I repair and sell, donate or just call it a day and sell it for scrap? Not sure if I could sell it in its current state. It’s an “extra” car and no longer needed, but sucking up too much time and resources. Any recommendations or thoughts about next steps? Thanks
Gang I'm not sure this is the best forum for such a topic; 2008 or 2009 GX470, as of now what is the recommended path for converting to a hard metal suspension system, all 4 ? This will get mild offroad use on trips to remote areas, but 95% typical town & highway use, with quite a bit of rough 2-lane paved backroads.
If I need to inquire elsewhere, links appreciated!
I have a 1994 Ls400 with an odd suspension squeak. The squeak only happens when braking. Definitely not a brake squeak. The squeak sounds more like a chatter and gets louder depending on how fast I'm braking. But this squeak does not happen when in reverse. I've replaced the UCA on the driver's side because the ball joint boot was torn. Both front struts are brand new, and just today I took the sway bar bushings off and greased them. Sway bar endlinks don't have play, and the rest of the ball joints don't have play. Still the same noise. Any suggestions on what it could be?
