Maybe someone can help...I have an 04 Durango that is running at 500-600rpm and on occasion it will die. Code reads that the O2 sensor was bad so I changed it. 10 minutes later check engine light is on again and it is idling low again. Code again read that the same O2 sensor was bad. So I am wondering what else could it be? I am going to change out plugs and wires this weekend to see if that helps, but I am at a loss now. Any suggestions?

 

Clean the air intake and check the throttle position sensor while ypu are changing the plugs,

Thanks for the suggestion. I will do that. Again Thanks

 

No offense intended, but are you changing the correct sensor? There are two pre-cat O2 sensors, and both aren't easy to get to.

 

Non taken buddy...The code keeps reading the O2 sensor after the cat, I changed the one before the cat last year, and it was a pain to get to. You say there are 2 O2 sensors before the cat? Maybe I am missing something. I will look at it some more when I change the plugs this weekend. Hopefully I get it figured out soon.
