Re: 1995 vs 1996 ECMs and drivability improvements...seems the problem of the rough transmission shifts was apparent to Lexus in the 1995 models, but maybe the connection to the idling-to-standstill wasn't made until the 1996 owners started reporting. Anyway, the TSB that applies to 1995 LS400 is recapped below. Technical Service Bulletin EG003-96 October 7, 1996 (OPCODE EG5002 requires the ECU replacement, cruise control computer, and spark plug replacements as a set for the 1995 LS400). LS400 DRIVABILITY IMPROVEMENT - To improve driving smoothness at speeds above 40 miles per hour, the following components have been changed. Applies to all 1995 vehicles from JT8UF22E*S0O: Old part / New part / Application 89661-50220 / 89661-50224 / ECM Fed. (veh prod 9410-9502) 89661-50221 / 89661-50224 / ECM Fed. (veh prod 9502-9507) 89661-50230 / 89661-50234 / ECM Cal. (veh prod 9410-9502) 89661-50231 / 89661-50234 / ECM Cal. (veh prod 9502-9507) 88240-50070 / 88240-50071 / Cruise Control Computer (veh prod 9410-9507) 90919-01180 / 90919-01178 / Spark Plugs (veh prod 9410-9507) Thanks, Lee I believe Lee refers to the correct Service Bulletin for the 1995 LS. I was not aware of the Cruise Control Computer and Spark Plug Replacement when I took mine in. I have since contacted Lexus about this and they were aware of this. The Service Mgr will call me when he returns from vacation.
  2. Lee, Thank you for the information on the 1995 Service Bulletin. I just spoke to Lexus. The Service Rep that handled my repair said that he told the serivce mgr they should replace my cruise control computer and spark plugs as well. He said the serivce manager told him not to do it at that time. The service mgr is on vacation and will be calling me back when he returns. The service rep also wanted to know where I heard about this. :D
  3. The service mgr was very nice and never questioned the fact that I have a 95. I believe this is a common problem and Lexus does not wany any trouble in the event of an accident.
  4. After long periods of highway driving does the car die when slowing down or coming to a stop?
  5. Yes I have taken many long highway drives and this fixed the problem completely. I also had the problem of rough shifting in and out of OD sometimes. This was fixed also.

  8. Please refer to post by JOldaker dated 12/11/2003. You will find a reply by Pachocco1 that was very helpful to me. I simply advised the service mgr. of this service memo and he contacted Lexus HQ to see what they would do. I have been trying to add this address to my replies to you but I must be doing something wrong because it dissappears everytime I attach it. Good Luck
  9. I had the same problem with my 95LS. Also mine would die after driving for long distances at highway speed then coming to a stop. It would then start right up and idle perfectly until I drove for long distance again at highway speed. The transmission problem went away with the replacement of the ecm. My 95 has 95000 miles and Lexus warranty covered repairs up to 80,000 miles. I then had to pay 1% for every 1,000 miles over. Total cost to me was 15% or $250.00. Lexus did not test drive my car because they said it would take to long to duplicate the problem. If you have to replace the ecm this might save you some $$.
  10. Lexus of Clear Lake replaced my ecm in 1 hour this am. Service Mgr was very nice and said he had never seen anyone get this part replaced for this price($249.00). They even washed the car when they were done. Thanks again to everyone for the advice.
  11. Lexus service mgr called me back today and said Lexus would warranty this job up to 80,000mi. Then it would cost me 1% for every 1,000 mi over 80,000. He estimated 95,000 mi on my 1995 would cost me appx $252.00. I told him to order the ECM and schedule the job for next week. I feel this is a great savings and appreciate the valuable info from this forum.
  12. I talked to Lexus service manager today and he is trying to get my 95 ls400 with 94,000 miles covered by warranty... He will call me back and I will post the results. He was aware of the tech service bulletin. Thank you pachocco1 and lexusing for this valuable info.
  13. Jamie, Did you ever get this problem resolved???
  14. I have the same problem with my 95 LS400 91,000miles. I have been advised to clean throtle body and add bg44k to the fuel. I believe it is related to idle control in my situation.
