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.

well i had a 98 dodge neon that seems like it did the same and it said engine misfire and all i did was due a tune up change spark plugs and wires.

This is a safety feature that the vehicle brings. You need to reset the E.C.U on dealership or it will keep doing it to you. It was probably caused by one single time that you did not closed the fuel cap correctly. Good luck

There could be a couple of reasons for this. If you are getting multiple misfires then usually it has something to due with the plugs going bad. It also depends on how many miles you have on the plugs and the wires. The other problem could be with the ignition coils or the ignition module.
