What would cause a 2003 Hyundai Sonata 4 cylinder to misfire and die?

Asked by Apr 11, 2015 at 01:51 PM about the 2003 Hyundai Sonata

Question type: Maintenance & Repair

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.

1 Answer

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?
