2010 Hyundai Accent Q&A
2010 Hyundai Accent Question: Why does my 2010 Hyundai Accent keep backfiring?
Check engine light kept coming on and when the vehicle is taken in, the technician cannot find a problem (typical). The vehicle has been taken to a Hyundai dealership for the same problem more than three times. The last time a coil was changed, the check engine light does not come on anymore, but the car continues to backfire. - frustrated hyundai owner
could be another coil has gone bad. seek another diag and est. have them read misfire data with scanner - globalhelper
