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!
At about 2am at night my car starting randomly ticking. It wasn't running or anything. After I unlocked it to try and start it, it started making the same ticking noise and wouldn't start. When I turned off the ignition the noise started again. It was coming from around the bottom of the firewall, between the engine and transmission. I touched the battery and it was awefully warm so I took off the positive terminal and it stopped. I would guess it's the starter but I don't know why it would do that so randomly.
Edit: it did the same thing about 15 minutes ago, but this time the lights were flashing and siren went off. Can it be the antitheft?
Here's how it sounds. With ignition and keys out.
Retiring at 68 and thinking of selling my Honda Odyssey and getting a true Luxury car; a Lexius. Zeroing in on an older ES 350 or RX. Maybe even a Hybrid one.
So, I ask you experienced Lexus owners, is this a bad Idea for a single woman who can’t fix her own car? And the closest Lexus shop is 2 hours away?
I’d like to keep the price around 25,000 or less.
Thank you for any insights, advice, etc
Have any you guys had a problem with the Rack&Pinion?
I went to the car service around my house(Knoxville, TN). They told me mine is leaking and needs to be changed.
I'm having a hard time deciding to change or not because it cost like 1500$
Do any of you have recommendations or any other place I should have service?
