A newbie here, just bought a 1991 LS400, 100k miles. Looks like showroom new runs great but a couple of questions. Suspension seems soft, normal or time for struts/shocks? A slight ticking, which my mechanic said ignore and Lexus service said was fuel injectors has gotten a bit louder over the 500 miles I've driven it. Valves, or anything to be concerned about? Temperature rides at midpoint of gauge most of the time but occasionally kicks up to last mark before overheat, then slides back down. Could this be faulty thermostat? After sitting overnight, steering moans just a bit when backing out of parking space, then is OK thereafter. Finally, transmission seems to have slight vibration after shift to third, from 32-36 MPH, not noticeable when accelerating to highwat sped, just when maintaining speed in that range. I know that this is an 11 year old car. Am I just paranoid or should I worry about any of this.
Thanks,
Kyle
