I've already done my research. So about 2 weeks ago my car was running really rough and I knew it was the coilpacks/plugs. Changed those out and the car ran fine. I drove to Texas from Mississippi (about 3,000+ miles) and the car was still fine. After riding around, I noticed the car was running rough at idle. Only thing is, the rough idle isn't even that bad. So I bought a new PCV hose and changed that out today, and cleaned the orange gasket. Still running a little rough. But what's weird is that sometimes if I start it up, it'll run rough, and then go away after a few seconds. The CEL light is on, has been for a while. Not really sure what to do now. Any suggestions/ideas on what the problem could be?
EDIT: By the way, the car drives completely fine it's just the rough idle.
