Hello, Sorry for not responding earlier, but I have lost a lot of enthusiasm for this forum because of the lack of responses to my question, which I considered to be a "bread and butter" question for a forum of this type. This has led to me not checking this forum as regularly as before. It seems there are almost no people here with the backbone to stick their neck out. Having said that, I appreciate your reply. Yes, I have been closely watching Unibee stock. One problem is that they are in Melbourne, and I am south of Sydney, and it would take some effort for me to get there if I purchased from a yard in Melbourne, or Adelaide, or..... It is a possibility, but it would not be my first option. There are any number of "import" yards in Sydney that offer the same service as Unibee, if not necessarily having the same levels of Hybrid offerings. Secondly, I believe that I can get a car for a lower price trying to import it myself if I find the right importer. I believe that I have found one, south of Sydney, that often gets cars delivered to Port Kembla, which is only 45 minutes drive from me. Delivery to Port Kembla is not the #1 priority for me, but it does help lower the ultimate cost. Again, thank you for your reply, and I am looking forward to seeing more of your posts about keeping your 600 running well. Does anyone else have any "importer" insights? Lexyhybrid's posts are just what I am looking for.

Not too familiar with the LS600h but there's usually a way to force these cars to run on engine power while up to temperature and stationary.

Just a little update...I cleaned the two MAF sensors, easy to remove them, squirted them with MAF sensor cleaner, dried and put them back. They seem to have improved with reading around 5 g/s, which is spot on. But hard to tell because if you take a reading when the engine is idling cold the engine has to run rich...and if you wait till it's warm, and car stationary, the engine switches itself off, has the hybrid does.

Rich, curiosity would get the better of me -- even though some cars appear to be going beautifully, I'd need to confirm it to myself. Kinda like when you're feeling hot, but it takes a thermometer to tell if you have a fever.

Mercedes M112? Changed the 12 plugs on my old CLK with a fairly serious hangover. What an absolute cow of a job. I had to keep having a little sit down 😄

For my sins I ran a BMW E39 a few years ago during rare time away from Lexus. Plagued with all sorts of gremlins, I used to borrow my friendly Lexus specialist's scanner. One day he asked me if I had dash lights on, I said no and he said stop using it then. There lies madness!

I already have proprietary MAF sensor cleaner on hand for another project. But carburetor cleaner, brake cleaner, degreaser or even low-grade isopropyl alcohol should not be used on the sensor. They either leave traces on the wire , which will affect the reading, or they could damage it. So MAF cleaner is the way to go.
