  1. I brought my lexus back to the shop this week. They found that my fuel filter was completely clogged up and that there was particulate/trash in the gas tank. They replaced the filter and sucked out as much trash as they could. It is running great now.

    I always use a good 93 octane gas (Shell or Exxon or Chevron)so i am not sure where the trash came from. I bought the car used so I will never know.

    You might have someone put a fuel pressure gauge on your car to see if the pressure is declining as it idles.

  2. did you ever find out what was causing this? My 2004 LS 430 does the same thing.

    My LS 430 seems to have a late shift into gear after descending a hill on a road or out of a parking lot. After pressing the gas pedal it seems to kick into gear a little late. Is this normal? Solutions? Thanks for your support

  3. I have been experiencing the same thing on my 2004 LS430. It happened for the first time about a year ago, but the check engine light would never come on and the repair shop told me the same thing: they could not diagnose it unless they could experience it or get a check engine code. Just last week, it became impossible and dangerous to drive and the check engine light finally came on and I brought it in to the repair shop.

    They said that there were several codes recorded but that they thought the air flow sensor was bad.

    They replaced it, but it stalled again on me yesterday so I am back to the drawing board.

    I have a '92 LS. It has 173,000 miles on it. For the past couple of years, it has developed a really annoying habit. When I have been driving it for a good while or on a highway trip, the engine seems to start chugging and acting like it's not getting any gas. It acts like it wants to cut off, and often does. As long as I remain at highway cruising speeds, this does not occur. But at city traffic speeds, and more frequently on inclines, this chugging and engine cutoff seem to occur. I try to stomp the accelerator to try to give it more gas, but this only makes things worse - the car will then start lurching violently and the transmission slams hard. The only way I have found to keep it running when it does this is to put the car in neutral and punch the accelerator, and the engine will always rev that way. Then I have to put it right back into drive and force the car to move forward. Obviously this is very hard on the transmission. I have taken it to Lexus. They say they can't diagnose it unless they experience it. And they can't test drive it long enough to make it happen. I have also taken it to three other mechanics who have said the same thing. My Dad experienced the same thing in his Toyota Camry, and it turned out to be the EGR valve. I have had people tell me that's what they think it is. But I don't want to shell out who knows how many hundreds of bucks to replace that if it isn't the root of the problem. Has anyone else experienced this, or does anyone know what might be causing this? It's making me CRAZY! And it's a dangerous problem in busy traffic.

    Thanks!

  4. Hi. My air conditoning on my 2005 LS430 is warm at startup for about 10 minutes, and then gets colder. Vehicle has 33k miles on it, just out of warranty.

    My Honda Ridgeline is cold at startup, that's the basis for comparison, so it's not my imagination or anything.

    Can anyone suggest what the problem might be, and what I should tell the Lexus dealer when I bring it in for service?

    Thanks in advance.

    My 2004 LS430 ac also takes a while to cool the car down when it has been out in the sun. It takes much longer to cool down than my other cars. I had it checked and the ac was fine. I now put one of those sun screens in the front window when parked in the sun and that has helped tremendously.

  5. When the compressor cycles on, I can hear the refrigerant flowing at idle. The sound is like a quiet high pitched squealing. My wife said it sounded like water. The Lexus salesman and service adviser couldn't hear it. Anyone know if this is a common issue and if it's normal? It is annoying. I expect the car to be perfectly quiet during idle. If I turn off the A/C, the noise goes away. It comes right back when the compressor cycles on.

    I can also hear refrigerant flowing when I am stopped in my 2004 LS430. I was concerned when I first got the car about a year ago, but it does not seem to affect anything; it is just a little annoying.
