    Whilst on my big Road trip cruise: control at 55 getting 30 and a half mpg with a 16 foot canoe on the roof I notice a check engine light...

    Under boost and knock sensor which are 2 codes that have come back 3 times now. I will admit the Boost after being on cruise control for a while I felt pretty chunky Lumpy when I stepped on the gas here and there.

    Turns out the pipe from throttle body to intercooler was loose, it popped off going up a steep grade. 10 minute fix.
