throttle body Plate issue
LS400 2000 model,
I have noticed that throttle body Plate does not open fully at all. I think something is wrong? any one have same problem.
This is the maximum throttle body Plate opening in my car when i turn using hand the throttle linkage to maximum open position.
My problem/question is similar to what this person having.

i could not find any lexus throttle body videos on youtube. Opening is done manually by turning the throttle butterfly.
PureDrifter,
you have LS400 why don't you check your car' s throttle body and report back.

Repair manual says that standard throttle valve opening percentage with full accelartion applied should be 60% or more. but in my car its not more than 25%
