Trim codes indicate the engine either running rich or lean, depending on the code. Many possibilities including vacuum leaks, mass air flow sensor, fuel pressure issue and pcv valve.
Anyway, I would not guess at this as guessing is expensive and usually wrong. It would be cheaper to have it diaged correctly and then decide to fix it yourself or have a shop do it.
