    Check my post dated March 17, 2018. If you can't get them there let me know.

    Inner tailgate lower trim

    New ones available on the internet for about $175. Your best bet for finding a used one is going to be auto salvage yards. That series RX300 was very popular and I suspect they shouldn't be hard to find in a salvage yard. Here locally, Pull-A-Part can be a great source for used parts.

    I believe those three .PDF files are active again. Let me know if you have any trouble downloading them

    Unless you're a hardcore DIYer you're getting into an area where you probably need to know a reputable independent Toyota/Lexus shop. I think the #2 cylinder is in the front bank of cylinders so at least it'll be a LOT easier to access. Still, with only 120K on the odometer you could pull the head(s) and pony up the $$$ to address the problem and you still should have a LOT of miles remaining on that drive train. I think my 2000 RX300 AWD had about 245K on it when I traded it in on a Tacoma. I did have the transmission rebuilt at 135K and it was still going strong when we traded it. When you find out what the root cause of your problem is please post a follow up so others can benefit from your experience. Good luck..!!

    If all this started quickly it's probably not a compression-related issue. Have you checked to be sure the #2 coil is actually firing..?? You didn't say anything about having replaced that coil and they are a weak spot.
  6. The first order of business is to determine exactly what the actual oil pressure is. If, in fact, the oil pressure is low enough to cause the oil pressure light to come on then you are at great risk of trashing the motor if you continue to drive it at all. Out of curiosity, why did you replace the oil pressure sending unit in the first place? If the oil pressure light was exhibiting the same symptoms before you replaced the sending unit then a failing oil pump would be in the lineup of usual suspects. A pressure gauge attached where the oil pressure sending goes will tell you whether or not you have a serious pressure problem. Good luck.

    By 160K miles I had already replaced two coil packs due to failure. After another one failed I just replaced the rest of them preemptively. Plugs are generally good for 100K miles so you are well past that threshold. A quick Google search on the codes will give you most of the info you need although the codes don't always point directly at the problem. Good luck.
  8. The most likely culprit is the Air Mix Servo. The above link provides some discussion but there is lots of discussion available on this subject. It's a common failure point for this generation of RX300 vehicles.

    A/C Light Flashing

    You may want to think about taking it back to him if you're comfortable with his ability to troubleshoot the system. This is going to require a level of expertise above shade tree. Good luck and let us know what the problem was.

    A/C Light Flashing

    How do you know it's fully charged? Unless you've put a set of manifold gauges on the system you have no way of knowing what the real story is. Sounds like a pressure sensing switch is causing the unit to trip out but you gotta put some gauges on it to know for sure.

    Breaks won't release after a stop

    Sounds like you have a problem with the ABS system. This may require a trip to a good independent shop to see what the codes will tell you. You need to stop throwing parts at the problem and go ahead and get it diagnosed properly. That said, at the age of your RX it was probably a good idea to replace most of the items you mentioned. I just traded my 2000 RX300 with 245,000 miles on the clock and still running strong.

    Strange Transmission Problem

    There is a safety interlock solenoid that will not operate unless the brake pedal is depressed. At the age of your vehicle it may be that the solenoid is "gunked up" and needs either cleaning or replacement. As to flushing the transmission with 208,000 miles on it, tread very carefully here. There is ample anecdotal evidence that using a flush technique on a transmission this old with this much service can break loose deposits that have settled out in the nooks and crannys of the hydraulic circuits and flushing may dislodge enough of them to lead to catastrophic failure of the transmission. If your transmission shop is really good they should have an opinion on this. This is especially true if the transmission has never been serviced or if if has more than 60,000-75,000 miles on it since the last service. This exact failure happened to me on a Jeep Grand Cherokee. A drain and refill is probably pretty safe but at least discuss this with your shop before proceeding with a displacement flush. Good luck. Oh, my Jeep lasted about 1500 miles before it failed. The tech found the ATF coolant lines completely plugged with sludge.

    It does not look good for the home team. Guessing the white smoke was oil blowing on to a hot exhaust pipe. You didn't mention whether or not the red Oil Pressure idiot light came on. I'm guessing it must have - assuming it is working. Sounds like your engine didn't stall; it seized.
