Title: puzzling and need some troubleshooting help
Post by: johnwoo on November 04, 2012, 09:36:27 PM

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?

edit: just did the stomp test and got 1215 Air Mass/Volume Sensor.  does that point to the AFM being bad?
