Question
The check engine light came on in my 1997 toyota corolla. The code showed p0303 misfire occurred in cylinder 3. What needs to be repaired. The spark plugs were changed in 2004 at 76,790 miles and the mileage now is 111,620.

Answer
Remove the #3 spark plug connector and check it for any signs of current leakage to ground, it may be cracked or show rust or burned through areas, a lot of times water will get in the spark plug tubes and short the connector to ground. if nothing can be found try replacing the spark plug wire set.
