All, I originally entered a post "95 LS400 TSB EG000396", but after finding this thread wanted to get on the band wagon. I have a 95 LS400 with 48,500 miles that has begun giving me problems. The course of events are as follows: 1 - Began experiencing "off throttle shock" and occasional stalling followed by a reluctance to start. Car would start after 30 minutes or more. But, car was not necessarily "warmed up" to operating temperature. 2 - Got a MIL with flashing TRAC light. 3 - OBDII scanner indicated ECT sensor faulty, but subsequently, following my Lexus shop manual, ECT sensor checked SAT. 4 - Checked wiring harness and all checked SAT. 5 - Tucked tail and took my car to Lexus. They pulled the same MIL code = ECT sensor. Lexus told me the ECT sensor "is the fix". 6 - Changed ECT sensor. 7 - Got a MIL with flashing TRAC light. 8 - OBDII scanner indicated ECT sensor fault. 9 - Car has deteriorated in ability to stay running when off-throttle, experiences dramatic off-throttle shock at even low speeds and shutters with constant throttle at times. It idles at a very low rpm and stalls if not coached with the accelerator. Once stalled, it is difficult to start - even after an hour. Is this a classis ECU issue? My LS has ECU 89961-50220. All underhood connections, fittings, plugs, fluids, etc. are in SAT condition. I have seen reference that TSB EG00396 may be honored by Lexus. If so, by which dealer/service centers? The local dealer in my current locale has proven useless - even after the ECT sensor change. New news - Lexus USA has stated they would entertain a "good faith" remedy once I'm back in the states. I'm on Guam until Aug05. HELP, please. Robert
