Have a 2004 Hyundai Santa Fe 3.5L v6. Added a fuel injector cleaner with a new tank of gas and now experiencing rough idling and getting error codes P0300, P0301, P0303, & P0305. What's going on?

P0300 is Random Misfire. 01, 03 and 05 narrows it down to those cylinders.

Clean throttle body and MAF, you may have carbon flaking off and fouling plugs. You could try taking it for a good thrash down the highway for an hour.

P0300 Random/Multiple Cylinder Misfire Detected
P0301 Cylinder 1 Misfire Detected
P0303 Cylinder 3 Misfire Detected

I would check out the EGR valve. That maybe what is causing all the misfires.
