I have 2 codes,O2 sensor bank 1 and evap, have any suggestions 2 do 1st?

i would clear the codes see which one comes up first, the evap code could be a air line broken somewhere what are the specific codes you are getting?

if you have a 4 cyl i had the same problem there is an overdrive button on the gear shifter click it till you see od /off on your tack and mine went off ive been drivin like that for a year no eng light ive tried higher octane but it came back on dont ask me how but it worked
