I have a 2004 Ford Ranger 4liter with 37,000 miles. One of our four oxygen sensors is stuck (that is what the code said). Can I replace JUST the bad sensor or do they all need to be replaced together?
Thanks for your help!

 

[sm=welcomesign.gif][hr]At $60 each I would just replace the one it should be fine.

 

Thanks for the advice!
