[QUOTE="Duster, post: 461259, member: 20812"] You might have to check the intake manifold. That code is not in respect to an "02" sensor but to an [I]O2[/I] sensor. O2 is shorthand for oxygen in its diatomic molecular form, necessary for combustion. Rough idles are definitely related to combustion, either oxygen supply or fuel supply. You have addressed the potential ignition issues. You don't mention whether it is an upstream or downstream O2 sensor, the first is measuring what is being exhausted from the cylinders, while the second measures the effectiveness of the catalytic converter. With a rough idle, I would suspect the specific O2 sensor is up stream. If it's on the same bank as your misfiring cylinder, you might have to consider some more heroic work on the motor, removing and inspecting the intake manifold, and the air cleaner works. Another problem could be the fuel pump or the injection systems. [/QUOTE]
