Thats why i was checking the codes. I think it reset because it displayed it before i cut it off, and now it just says done. Dragging may not be an appropriate description. It feels like an intermittant loss of power with a kind of stutter. It feels like something is opposing maybe which is why i mentioned the air filter because i thouht perhaps it could be an airflow issue. I initially thought it was bad gas and i went and filled it up with high test. The engine light went off after a couple of days and then it came back on and started doing the same thing.
