What year and mileage?
Next steps would be a compression test and swap injectors.

Oil control valves...

+1 on what 01LEXPL said. That was my issue, and that fixed it immediately. Which cylinders are misfiring? That determines which bank you need to replace

^ I'd do both.... its 100$ all in [from rockauto] and about 5-10 mins of your time.

I was in the same boat, changed three coils, two drive cycles later - again! Did my reading on the internet, and here. Turns out it was the OCV's.

Sucks to hear you went through all of that... you aren't the only one either, there's many threads like this where guys' spent all this money yet it requires a quick fix [in most cases anyways]

Lexus master tech here,

I hope the OCV's fix your problem, but I have seen valve guides needed to be replaced on the 2007 ES model. Just an FYI. Best of luck.
