2000 es with 129k miles. I noticed it just wasn't running as smooth as a Lexus should. It was shifting a little rough, accelerating slow and braking like ****. So I did a few things...

Put a new OEM Pcv valve
Flushed and replaced all fluids
Changed all brake pads and had my rotors done. The rear pads were the originals lol
Replaced the air filter

I try to change the air filter every few oil changes or so it wasn't disgusting or anything. I would have to pull up the service records to see the last time the fluids were touched, but I got the car with about 90,000 miles and this was the first time I did it. Maybe I'll just start flushing the fluids every year...

I also did the spark plugs and oil control valves at 120k miles. And the starter just a few months before that. So she's had some nice, fresh parts all done this year. I don't think I've put any non OEM under the hood either!

My car also vibrated when I was going 40 mph+ and hit my brakes but that went away.

You could have added cleaning the MAF sensor, throttle body, idle air control valve and EGR valve to make it more complete
