My son has a 2001 Accent (the largere 1.6 liter engine) that just started\nto misfire. He went to an Autozone and the guy there said the code was a\nmisfire in no.1 cylinder. He checked the plug and the plug wire and he\nsaid it looked OK. Could a bad injector cause this misfire?? What kind of\na job is an injector replacement??\n\nThanks for any help!
