Pulled P0303 code, but engine runs fine...whats the problem?

Question

Why would the engine run fine with a 303 code ?  Where is the # 3 cylinder located on the engine block?

Answer 1

P0303 Misfire cylinder 3

In the back middle cylinder. You may have to check the spark plug condition, or swap the sparkplug to a different easier cylinder if the misfire move replace the sparkplug.
