Default Engine running rough and flashing ses

this is what happened. car was running perfectly fine, I brought it through the top of first and into second a bit and then I let off. about a mile later the ses starts flashing and when I stop at a light its barely wanting to idle. It very much feels like a misfire. What should I check out first?

also it does seem to have a consistent ticking noise now, but i could just be paranoid cuz it always has some valve train noise....but it seems different now.
its an auto so it didnt over rev but idk?

You should get the SES light scanned and read. That will give you a good idea of what you need to fix. Its usually a misfire code if it flashes. Take a look at your plugs and wires first!
