While a Carfax is a great tool, it should only be used as a guide as it will not have everything listed on it sadly. For example, if there was major damage and the previous owner decided to fix themselves, it wouldn’t it make it to Carfax. Also, even if a dealer/mechanic fixed, they don’t always report to Carfax.

For limp mode, did you try cleaning the TB’s and O2 sensors? Even if the code didn’t appear, it’s well worth the try, esp. on a 2010.
