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?
