I keep getting code a miss fire code cyl #3 and getting raw fuel out of exhaust. On cold start up. Had cap rotor and wires, spark plug and #3 injector replaced. Still have miss fire in #3 and raw fuel out exhaust. When engine is at operating temp run nice no miss fires but feels like at times it is droping a cylinder at times Any ideas! No dealership has been able to figure it out.
