How to change an O2 sensor on my 2004 Dodge Durango with a 5.7 Hemi

Before changing out 02 you may want to try this if you use the low octane gas ( 87 ) all the time start using the high octane gas ( 93 ) had changed out my 02 sensor because check engine light said it was bad within one day light came back on saying same 02 sensor was bad to make a long story short started using the high octane gas and after 10 tank fills and light going off and coming back on 4 times now light is out since light has been out still use the low octane but not all the time switch back and forth between the low and middle octane gas.

Look on Youtube. You will probably need an oxygen sensor socket to unscrew the old one.
