Bad GAS = SES???

Hey guys...

A couple of weeks back my SES came on. I kinda freaked out..but found out it was throwing a P0304(?) code. It's the cylinder 4 misfire code. Erased it and then it would come back on. The idle ran real rough at about 8500 rpms. The other day I ran out of gas and had to fill my tank. I ran the car for a couple of miles and then one day after work I noticed that the SES light was not on anymore. It still idles a little rough, but no SES light and it's at about 9500 rpms at idle now. Any feedback/input on this? Anyone else run into this issue??

Plugs only had less than 1k on them. They were brand new iridium plugs. I'm not sure if they were bad plugs or not.

Maybe weak coils? I think you mean 850 and 950 rpm for idle...not 8500 and 9500
