Got my first is300 Saturday. Friend filled my tank with regular gas and on Tuesday driving to work my check engine light came on bad the trac off kept blinking. Took it to oriellys and had them check my codes.
These came up:
Filled my car with premium lastnight and light still on. I noticed some hoses unplugged on my aftermarket intake so I plugged then to where they seemed to go. I disconnected the battery to reset Ecu and when i went to start it, it was super sluggish. Feels like I pretty much lost all power. I un did the hoses I had plugged and seems a little better but still not all there.
Any ideas please?! Sorry new to the Lexus scene lol.

I wouldn't think a tank of regular would make everything go haywire like that, I think you may have other problems.
I think PO446 is the code mine throws now and then due to an aftermarket catalytic converter, not familiar with the others.
