A couple weeks ago, my wife was running low on gas in the Santa Fe and the car started having a mild misfire. We got the car filled up but the mild misfire continued. A short while later, the check engine light came on. The car is throwing the following codes:

P0300 - Multiple Misfires
P0302 - Misfire Cylinder 2
P0304 - Misfire Cylinder 4

There were no problems until the car almost ran out of gas. I have checked for vacuum leaks, visually inspected the spark plugs, etc. It's been over 2 weeks now and still having the same issue. Anyone know what the next step should be to get the problem fixed?
