  It is possible that your PCV valve or hose have foreign object or dirt in it. Or your fuel pump relay is loose.

  Or you can check your Air Filter for that, a clogged filter restricting air flow to the intake causes a rich condition. Just clean the filter and check for any disconnected vacuum hoses for it maybe a vacuum or air leak.
