As the title states I have a 2008 IS250 with 67k miles on it. Today my check VSC, check engine light, and VSC light came on. I tried cleaning the MAF sensor with MAF cleaner. I am wondering if it is possibly carbon buildup which I saw a DIY carbon cleanup at one point which I would have to find again. I was also wondering if the fact that it is 111 degrees today would cause anything or if I Should check my spark plugs. Basically trying to cover all my bases and probably some things that I should probably do at almost 70k miles. Any help is appreciated.

Check for codes first to see what it could be.

Just ran by autozone to get them to read what code I am throwing. It is a P2009

Anybody have any advice on what steps I should take to resolve this issue?

Update: I have cleaned the MAF sensor, replaced the o-ring on the MAF, checked almost every fuse, checked the gas cap o-ring (looks fine). I have cleared the code and it comes back. These are just some of the possible symptoms I have seen around forums. I don't have any symptoms of carbon buildup.
