Are you getting a CEL light coming on? How many miles on it? What makes you think it is the spark plugs?

engine light on dignost miss fireing 1 bank 64344 miles on car
The over head coil pack would be more specific to the cylinder. Ussually an o2 sensor refers to a bank or the entire side off the exhaust manifold
64344 miles is to soon to be replaced. I'm going with Heich25. 02 sensor.
Oh and replace them in pairs. If 1 go's the other's are on the way.
V6 or 4 banger? Bank 1 is on the side of cylinder 1(v6..) 4 banger has only one bank. make sure u have sensor 1 it will be the first one exiting the engine. Sensor 2 will be naturally after 1 downstrem
If you know the CEL codes, that would pinpoint between O2 sensor (P0137 usually) and spark plugs (P0300). If code is 137, then it could be a number of things including: -Oxygen sensor defective -Fuel system running very rich or lean - check other codes first -Engine misfire condition - repair -Fuel pressure very high or low - fuel pump or pressure regulator Last time that Clementine (my 2006 Orange Aveo) threw a P0137, I replaced 2 O2 sensors, air filter and catalytic converter before she cleared the code. All I can say is good luck!
