Re: Engine misses at idle

A misfire is not always caused by the ignition system. A faulty/dirty fuel injector can also cause a misfire. Try moving the #3 fuel injector to another cylinder and see if the misfire code follows the injector. Be sure to pick a cylinder that is not fired by the same coil pack.
