What would cause a 2003 Hyundai Sonata 4 cylinder to misfire and die?
For no apparent reason when driving it will misfire and die. We replaced the fuel pump and fuel filter, spark plugs, wires and ignition coils and it still runs rough and misfires. Any suggestions? Thank you.
Check engine light code reads misfiring on cylinder 2 and 3. Would a clogged fuel injector act normally and then momentarily cause a misfire? Is that possible?
