  1. Thank you for Reply. Now i didn´t start the Engine for 2 months, but I remember last Error was Multiple Misfires. I didnt hear Misfires but Engine was not running on all Cylinders. After starting cold all cylinders run, After warm up not all cylnders.. I will try next week and go to a Mechanic arround the Corner to Check pressure and for new faults in ECU.
  2. Hallo together, Please excuse I’m from Germany and can’t really speak English. I have a Big Problem and don’t know really what to do with my ls400 vvti. Last Year November I did by car for a good price from south Europe. A Region with Tempo Limits, car only about 100k Miles for a good price. I did get a cheap Flight and the Adventure starts. First Problem: Check Lamp (ECU) on. Seller told me no problem you just have to reset @ Lexus Dealer not possible here in this region. Its O2 Sensor, it’s changed. After starting driving home, heating is not working, I found not enough Cooling Water :( Ok I Filled in Water and did drive about 1200 Miles home. Everything seems fine. Did not need any more water. 2 Days later I did check @Lexus Dealer, of cause not possible to delete the faults in Ecu, not the changes o2 Sensors are the Problem, the other both AND the knocking Sensor. Ok with this Problem I did ask here before a few months. The Mechanic won’t believe that it’s really knock Sensor. The Engine of this car was changed 2 years ago (with less than 100k Miles!) - May they did make a mistake. Ok I didn’t know really what to do, didn’t move the car for 2 weeks. After this the Battery was low, so I did start with jumper cables. OK, after this all ECU Errors are away (now I did have obd2 reader), I did drive and wait for coming again. But only the o2 Sensor came back, no more knocking Sensor. (I did try to delete the Error before many times, always the same errors came back) So very nice two weeks, everything seems fine, may car runs better than bevor, may an illusion I don’t know :) OK but one day I did drive to Petrol Station, did tank up and start engine. Now I did hear some slight sound I did not know what is. And I did see white Smoke behind the car, ok this I did see before, but not so heavy. I did drive, after a while Check VSI comes, and the heating not works any more. I checked - Cooling Water Low. OK, seems like Head Gasket is damaged. But, is this possible? I did not make a high speed rive or something like this before, no overheat or something. Seems like the Sound I did hear are air in cooling system. Is this caused May by some other reason? I have many white Smoke on both Exhaust. If I restart car seems good for a few minites than again white Smoke and Cooling Water missing. No I really don’t know what to do. There are some more Problems, I can’t believe it all, I did by the car for using 10 years ion German Highways, I did read before its one of the best car ever build... Addition Problems are, Timing Belt has to change, Seller told me it’s new, but the company that change engine did not change. Lexus Dealer means that Steering is leaky. Two weeks later the Battery is absolute empty, no more light is burning in the car so may there is an additional electrical Problem. I don’t know if I can trust this car anymore. I may have a private Mechanic who maybe can change me the gasket. May can check valve and refresh Timing belt. But, what can cause this errors? Why a Head Gasket gets broken by starting the car? What with the knocking Sensor? I’m afraid there is another Error with this car and causes all this Errors. I did by this car as a 2000 LS 400, know I knows it’s a car originally build for Canadian Market, seems one if the first with vvt-i, Toyodiy means build 10/1997. But may engine is newer because it was changed. I even think about change complete engine, the old one from my car is repaired to sell now for years (in Germany there are about 100 LS400 with vvt-i, Lexus is rarely, parts are expensive I have to order in US ore UK) ) May I have a complete other Problem with the car, may any of you can give me a hint! Thank you very much, I hope you can understand my words. Please tell me if something is not to understand,
  3. Hallo together, first please excuse my bad English. My Name is Holger I´m from Germany and I did bought (may not a good deal) a 00 LS 400 with low mileage. but it seems the knock Sensor is not working. OBD Error: P0325 - Generic Type Powertrain - Ignition System or Misfire - ISO/SAE Controlled Description Knock Sensor 1 Circuit Location Bank 1 or Single Sensor I did found by searching: in http://us.lexusownersclub.com/forums/topic/31948-replace-knock-sensors/ You can change the knock sensors and wire harness without removing the intake manifold. Remove the EGR valve, PCV hose and you can get you hand into the V area of the block. A 27mm socket and small rachet with a flex head and the job is done. and in an other board: " IThe good news is that I just finished changing the right-side knock sensor, and the problem is fixed (no more pinging). It was fairly easy to change the sensor. The whole job including test drives took about 1 1/2 hours. I removed a couple of the plastic cover pieces between the manifold and the valve cover, and with a long screwdriver, gently removed the connector on the sensor (accessed on the right side of the engine thru the small openings around the manifold). I removed the knock sensor using a long 3/8 extension with a universal joint and a 1 1/16" sensor socket taped together to hold the tools together. I installed the new sensor using tape on the socket to hold it in place. FYI - The sensors are very tight in the block Read more: http://www.clublexus.com/forums/ls-1st-and-2nd-gen-1990-2000/183789-gen-1-ls400-knock-sensor-replacement.html#ixzz3sKFHmoMt " So my question i did not find an Answer: does this way to do the work similar with the VVTI Engine in the Late LS400? (Both up are for the older Engines) and may if any ever did change in the late Engine, did you use an OEM Part without Problems? Thank You!
