My 2011 Toyota is currently in limp mode which is a safety feature because I haven't figured out how to clear an error code.

It drives but it is currently restricting it's power for my safety.

I suspect it's gummed up with carbon deposits from recycling exhaust gases for the sake of the environment. I'm waiting for a plate to hamper the EGR before cleaning it out & clearing the error code.

The difference between the 2007 & 2011 model seems to be mainly the computer. I'm not sure I'd want a later model than the 2011.
