When I got my car it idled rough. So I took it to a oreillys and ran a scan. It said the front o2 sensor was running rich. So I replaced it. Now my car dosen't want to idle. It trys to stay running but dosen't. I also cleaned the idle air control valve. Now when I run a scan it says that no codes are present even while the check engine light is on. What all could the problem be or what should I check?

If it idles rough, start by doing a compression check to be sure the engine is good since you dont know its history. If it is running rough odds are good it isnt the o2 sensor, it is just reading the exhaust from an engine that isnt running properly. Check tune up if compression is good
