Idle to low

maybe it a dirty throttle body or a dirty mass air flow sensor

The proper thing to do that will save you the most grief is to have a proper engine performance diagnosis performed. You will find that there are codes in the memory of the engine's computer that will give clues to a qualified technician as to what is happening with the Canyon. Only then would I do any repairs -- guessing at a MAF or throttle body issue is just that -- a guess, and almost never causes a check engine light.
