Got an OBD Code P1110 today:

[NuQFO]

My service engine light went on today with codes P1110 and P1110 P.

My service history says that the Intake Valve was replaced @ 108,445 miles for the same P1110 code.
I purchased the vehicle at about 111,000 miles so this issue should still be covered by warranty. I have about 115,000 miles now.
I just cleared the code...want to see if it will come up again and give me a 'hard code'.
Oh, this also happened after filling up the gas tank today @ Chevron with their premium gas.

Any suggestions?
