help. i need to find this problem. ok im driving normal everything is fine. then all of a sudden my car starts to backfire and bog real bad. ok no power at all when it does this and some times i can floor it and it will go back to working fine then if i let go of the throttle it will go back to bogging. i got it scanned and i got these codes.
