I had my fuel injection system cleaned at Big 'O Tires. This my first set (just put them on). I just don't know what is up. My truck has been maintained properly as far as changing out things. What I don't know is what do do next. There is no codes. But it does misfire/hesitate/backfire when accelerating. Nothing seems wrong when at an idle or while in park and reving the engine up.
