Shatzy Posted August 10, 2015 Report Share Posted August 10, 2015 I continue to get error code indicating engine misfire, cyl #4. Replaced, plug, boot, AND front coil, but msg returns. This has been going on for several thousand miles. Car runs fine, 18 mpg, regular gas. What harm can this do to engine? Steve M Quote Link to comment Share on other sites More sharing options...
