    another idling issue: after not starting for awhile

    hey guys my car has been in storage and i've been neglecting it. today i went to plug the battery back in the car and to start it. the car fired right up but was idling weird like struggling to keep idle. then the engine check light came on and the car idle perfectly. i let the car warm up and unplugged the battery and waited 30 seconds before plugging the battery back. restarted and the check engine light goes off and the car struggles again to keep idle then the engine light comes on and it idles perfect.

    so im guess is the o2 sensor plugged up? im really a novice to this any help would be appreciated. it seems like when the engine light comes on the car runs great. does it mean im in limp mode?

    any ideas?

      stomp test showed code 1215 afm. how would i test for that?

      would the idle improve after the check engine light came on with shitty fuel? would imagine idle would be bad always.
