P0303 Misfire number 3 cylinder
When there is a misfire condition a cylinder is not contributing, being a 4 cylinder engine you now are working on 3 cylinder, most misfire condition are igniton related. Pull the number 3 sparkplug wire and check the condition of the ignition wire, inspect to if oil has entered into the sparkplug well causing the misire condition and also any secondary sparkplug voltage leakage
A ignition wire going into the sparkplug well should be check for oil entering into the sparkplug well , Most of the misfire condition are igntion related
