hey guys the wifes 2004 1500 4.7 v8 had the engine check light on so got it scaned at auto zone guy said the o2 sensor(s) may be dirty or have a bad ground or a short .So i took them out and cleaned them and they wernt to bad and checked all the grounds i think... un hooked the battery to clear the code works for my powerstroke not sure for dodge but the light went out , then about an hour of driving the light is back..and idles a little rough at stop lights , so should i just replace both sensors and be done with it or if there some other things i can do to fix it? thanks guys

 

What were all of the codes you were getting?

 

I cant remember...

 

Those will be crucial to know. Without those we can only assume and guess. I take it you dont have a tuner do you?

 

no i dont have a code reader. wish i did though guess ill just go get it scaned again and write it down.

 

The code, if for an O2 sensor will tell you which one is the bad one... So yeah, you need to know the code unless you want to do all...

 

you should be able to flash the codes on the odometer shouldn't you?
