On mine the idle is pretty fast when cold and causes the car to really pull when put in reverse-- was following this link to see if anyone else knows how to bring the "cold" idle down.

Dang this is bugging me -- my mechanic has a book that says my 1992 LS400 is an interference motor but I read everywhere the 90-94 (and above 90-97) are non-interference motors. If it is truly a non-interference engine (1uz) in my 1992 then I will probably just drive it till it or the water pump goes before replacing it. No problems there other than being stranded for a bit right? I really don't know why I am posting this rather than for warm fuzzies as I have read many people posting the same question and receiving the same answer. This is my first Lexus and I picked up a pretty worn out 1992 LS400 for $3.4k and will be attempting to bring it back into decent shape with my very rusty back-yard mechanic skill set which began with my first car, a 1959 Morris Minor which had something new broken or needing attention nearly every day. From what I read the LS400 has a reliability rating orders of magnitude better. I picked the LS400 for its comfort, reputation of reliability and because I've always loved V8s. :)

Thanks! I was trying to do the same thing but not as brave as you ;)
