    Power steering and smoking

    Thanks so much Paul. I am so grateful to you and this forum. I did the blocking off and it worked out. No smoking anymore. Steering is very free. Car moves smith again. I appreciate this forum that has made me continue driving my Lexus. God bless you all
  2. Please is there any connection between leaking power steering and smoking. My power steering fluid first began to short. Then smoke at first start. Now, fluid does not retain at all and I haven’t seen any leaking spot. Smoking is very constant as if from the Engine yet engine oil does not short. Please any connection between the two faults?

    Axil maintenance

    Please could someone help me with tips on how to keep the axil maintained. I have driven my ls400 for 29 months now without doing anything maintenance check on the axil. It doesn't have any problems but I feel I should ask to avoid a sudden breakdown.

    Idling problems

    I wish to thank you all. This forum has enabled me to keep driving and appreciating my ls400. I replaced the knock sensors accurately and it came off fine. Knock sensors has male and female and should not be misfixed. 2. Please could someone help me with tips on how to keep the axial maintained.

    Idling problems

    Thanks dear. I have succeeded in checking the codes. Here are what I got: 25=Air-fuel ratio lean malfunction 26=Air-fuel ratio rich malfunction 41=Throttle position sensor signal 52=No.1 knock sensor signal 55=No.2 knock sensor signal I know I worked on the starter motor montgs ago and thats where they may have tempered with knock sensors. It is a whole lot to get down where those sensors are I adjusted the the throttle position sensor and the idling speed came down better But I dont know anything about air-fuel ratio issue. Please how do I go about checking those issues?

    Idling problems

    Hello house. My Ls400 (1990) is no longer coming down after few minutes steaming in the morning. It stays up and I don't know what to to. And when I raise it or drive on, the check light comes on with TRCOFF
  8. I need assistance. My car (1990 LS 400) had problem with the RPM meter; it fell off and stopped working. I took it to an electrician who loosened out the entire instrument cluster, and he unplugged all terminals and even dismantled the panel. He couldn't get it done, instead, he spoilt more of the components - temperature gauge and Economy lights. My main problem is that thereafter, I noticed an erratic idling and entire movement of the car went slow and bad.. No one around here seems to...
