es300 2000 with 138,000 hard brakes and rough/low power engine
Not sure what is going on.
Brakes were first to notice that they became hard like to power assist.
Then rough idle to lack of power. Clunks from the engine area, not sure if trans or just engine missing so it is making noise.
No codes that say coil pack.
Got the code read and they guy just said air sensor.
Ran perfect before then poof....
I have had a Cam valve replaced and it runs kind of like that but lot less power and hard brakes.
Anyone else have this?

You probably have a vacuum leak in the intake system. Given the brakes aren't working properly, my thoughts are there's a leakage in the brake booster vacuum line going to the intake, if not a leakage in the booster itself.
