I swear, no placebo effect here. Had the same results when the 90k service was done on my LS400. Took it from feeling "like new" to "like it just rolled off the assembly line" and got rid of a misfire at idle on rainy days. Also, no PWR switch on. No full 90k service either.
Just a replacement of the timing belt, water pump, serpentine belt, coolant, and hood struts. Absolutely nothing else (as far as I know). Not sure how this fixed my braking issue (felt like they were worn out though new and would stick for a second before engaging sometimes, usually on hills) --or improved performance-- but I'm glad it's gone.

I did mine at 86k and 12 years....everything looked new. I guess this is just something nobody likes to spend money on. I bet > 50% of the used LS430s for sale have never had this service, as the owner dumped the car prior to spending the money (at a dealer potentially $1800). I guess changing this thing is how I felt changing my BMW brakes at 49k. they really didn't need them, but since I already pulled the wheels and took the rotors off, I changed them all. Regardless of if we can afford it, part of it feels wasteful. The rears were about 75% gone so changing them got rid of a squeak squeak squeak. The fronts were not even 50%...

The services you mentioned above will not alter or enhance how your engine operate, and definitely unrelated to your brake system. Nonetheless, your perception is your reality, so congratulations for the excellent outcome!

And that's the important thing. The car feels good and the problems have been alleviated..

Just my speculation, but I think Lexslexus has benefited from the brake service (braking issue somehow resolved itself), and a new air filter (acceleration is much quicker). Air filter is a key part of the engine’s respiratory system. A new filter will rescue an engine from operating in a suffocating state due to a clogged filter. Just my 2-cents worth to explain how a sluggish (initially unbeknown) engine can be restored by something as simple as a clean air filter.

2KHarrier and Gronemus, I apologize for debating that the 90K service “can” restore engine performance and address brake system issues. Turns out, Lexslexus confirmed that my speculation was incorrect, and that the brake service was not done, and the air filter was not replaced.

I'll second that. I'm no expert by any stretch. As Gron stated, you brought out valid points. I'm just glad to read through a thread that isn't completely loaded with off topic comments ..

My dad was an aeronautical engineer, and as a teenager, everytime I changed his oil (man he trained me well, I should do the same with my son, he's 4 now, although times have really changed, I doubt more than 25% of HS students could even change a tire today), he told me each time, "the car runs much smoother now." He smiled, and winked. Whatever that meant (I did ask him decades later)

Just chiming back in because I recently had my 90k service done a few days ago. Wanted to add that just because you think your timing belt is fine because your car is driving great doesn't mean it's not. Prior to getting the 90k service out the way, my car was driving so good that I thought the timing belt & water pump might have been changed a year ago. Now that they've been replaced, what a HUGE difference. The whole car feels MUCH stronger, way faster, acceleration is much quicker, and a braking issue somehow resolved itself. I'm saying all this to say, don't let your LS fool you. Go get the 90k service done.

Sure, this stuff is $5.95 and maybe next time I'll DIY. But for the first time, I used Toyota WSIII, which cost 6X as much, but was worth it.
next time
