  1. Hi all, I'm going to replace the TPS for my 99 lx470 because occasionally, the accelerator does not produce any power eventhough I press it all the way to the floor. At the same time, the engine is still idle. I have to turn off the engine and turn back on to get it working again. Could anyone advise me how to replace the TPS? is there any special adjustment or alignment? Thank you
  2. Yes, It just cost me $1100 for 60k service on my 99 lx470

  7. I went under the car yesterday and found that the whole exhaust system vibrates when I shift gear to D or R. The vibration from the exhaust transfer to the frame and cause the booming noise and vibration. Can someone check with the dealer so see if they see common problem with the exhaust dampers? are there better dampers to replace the existing ones? 99 lx470
  8. My 99 lx470 is behaving the same started about a month ago. Please help if you know the root cause is. If I shift to park or neutral, the vibration noise stops.

    I removed the rear seat but I could not find the connector they described. All I saw was wire bundles and I checked throughly on both sides but no sign of the connectors. I tapped on the wires and the connector to the amp, but It didn't help. suddenly this morning when I started the car It worked again. There must be ghost in my car.

    VMF, UCF, I have a good news for you. This morning when I started the car, the volume works as good as before. I don't know how long it will stay good. However, I still like to figure out what caused the problem in the beginning. I found this link on the web. Check it out. I tried to look for the connector they described but I can't find it. Thank you all of you who's trying to help me. http://carstereohelp.com/repairDoItYoursel...usRepairVol.htm
  11. :( We discover some problems with the power window on my wife 99 lx470 since we bought it last year. First, the power window on the front passenger go up all the way then automatically go down for about 6-8 inches. Second, the power windows on both of the rear are so weak when they go up, especially in the cold. I have to physically assist the glass up with pushing the up button at the same time. Anyone out there know how to correct the problem? Thank you very much.

    I got this lexus just a couple of weeks ago. I will try to remove the head this weekend when I am off from work. What do you suggest me to do after I remove the head unit? I appreciate your help.

    thanks for reply VMF. It is the same for AM/FM and tape. I did open the trunk and check the wire bundle to the pioneer amp. Everything looked intact. I tapped the amp and the wire lightly with radio on but nothing change. I'm wandering if it is because of the amp failure?

    91 lexus with pioneer sound system. The radio turn on but the sound output is so low. I turn the volume up all the way but I can barely hear anything. All speakers output some sound but very low eventhough the volume is max. The problem has been going on for a week. I check all the fuses and they are ok. Thank you very much for your help.
