After getting my evap problem out of the way my check engine light came back on.. scanned it and the code P0303 (Cylinder Misfire) came up under "Cylinder 3". I've never come across this problem before and dont even know where to start. A lot of people are saying plugs, wires, even someone was talking about a power steering leak that some how interacted with it??? Any way that caught my eye because I do have a small leak in my power steering.

Any help would be appreciated... Thanks in advance!
