SOURCE: #5 cylinder misfire

I have a corolla and had #4 cylinder misfire also diagnosed at autozone. After changing the spark plugs, problem persisted, along with the same error code, so they recommended changing the spark plug wires, and that is what fixed it. I would have changed the rotor cap too, but was low on dough. Glad that was not the problem.

could be the type of plug you are using.I was told only to use ngk plugs.I recently put bosch plugs in my mazda 3 and the check engine light came on and it started missfiring.

Hello there, As far as the check engine light I would think since you mentioned it shacking that your light will probably be on for a misfire, Meaning most likely you have a spark plug wire going bad. I would stop by somewhere such as Autozone for a free check to tell you why your light is on just to double check.

Your fan issue could be several different things such as the fan motor going bad or the blades could be rubbing something, that one is a little tricky without hearing it.

Good Luck and I hope this does help you some. Allen
