    What year? Any mods? Could be a lot of things.

    clean out your throttle body
    PCV valve (good chance)
    Engine management. If you installed a new sensor, this could be the culprit. Any way you can log your parameters?

    Please google PCV valve rather than have me educate you. It'll be easier on all of us.

    What engine management are you using with those modifications?
