Plugs
plug wires
cap and rotor

Did you check them or replace them? Things like cap, rotor, plugs, and/or wires can look ok but be malfunctioning. Have you reset the code to see if it comes back?

I replaced the plugs, plug wires, and upgraded the injectors from 310's to 440's. The only thing that wasn't replaced was the cap and rotor which was checked by the guys that did the work to my car. I have disconnected the battery but the code come back.
