Hello LOC New to the club, I thought this would be the best place to be with an older Lexus LS400 trying to keep her on the road witch she holds quit well, fun to drive New to an 91 LS400 with some miner problems that I'm trying to sort out, 1st is one of the knock sensors ( Bank 1 ) ? under the intake ? I've been trying to find a Repair Manual, But nothing at local auto store. If any one can supply/point me to an Exploded top view for the 91 LS400 it would help. Thank you for your time
