I am having some issues with my dodge and cannot seem to figure out the problems. I am having a problem with rough running the longer I drive the vehicle and a sweet/gaseous smell coming from somewhere. My truck was throwing a p0175 error code. After I checked for vacuum leaks, replaced my tps, pcv, checked fuel lines and the map sensor I decided to change my o2. So I replaced the passenger side, before the cat, o2 sensor. When I pulled out the sensor it was carboned up pretty bad. Now my truck is throwing a p0051 error code (the heater sensor on the o2 sensor) on the one I replaced. I had put in a Bosch o2 and a dealership told me that I needed the original chrysler o2 and everything would run just perfect. I am skeptical. I am going to replace the o2 sensor but I think that there is something else wrong because I am still getting that smell.
Usually if it is a heater code, it is the sensor. Has the truck ever been tuned up? If so did you use factory parts? The original code was rich bk2 sensor 1.

I am sorry the original code was a p0174. I realized this after your reply. I recently put in new spark plugs along with everything else that I previously mentioned but other than that it has nothing else done. I will replace the o2 sensor with a chrysler one if I can.

What brand of parts did you use?

I used champion spark plugs and a bosch o2 sensor. The tps and pvc are the standard ones sold at autozone and oreillys autoparts.
