Having problems with your 2003 Toyota Corolla ?
Tune up / does my car have wires or just spark plugs?
No it does not have spark plug wire's, it only has ignition coil boots. Just replace spark plugs, if engine not running with a cylinder miss you'll be ok, if it is running with a cylinder miss you might want to check your ignition coil pack for spark.
