lol ok i still dont get the code thing ill just take it to a shop so they can check for codes all thought theirs no check engine code that stays on their is one time tho that it comes on and then it shuts off by itself and then when im driving it will come on and then just leave in a little while

it's easy to blink out the codes.. but if you feel more comfortable a shop scan it then by all means do it...and any codes that come and go should be logged in the ecm's memory
