As you can see by the subject I have a 2002 Dodge Ram 1500. Its a 4.7L V8 and for some reason I have black smoke coming out of my exhaust. Black smoke comes out under hard acceleration as well as when the truck is started. In some cases black smoke comes out when idling as well. OBD-II gives me a P0171 error, which I was doing some research and found that it could mean a bad O2 sensor. Could this be the cause of the black smoke? If not does anyone know of a probible cause?
If someone could assist me is finding the culprit it would be GREATLY appreciated.

Thanks,

Putnam

The O2 sensor could be the cause, but tests are needed unless you just want to gamble on that being the problem. The PO171 is for bank 1 being lean. Here is a list of items that may cause the code. The O2 sensors are last on the list.

Intake/exhaust leak, AIR system, MAF/VAF sensor, fuel pressure/pump, injector(s), HO2S



Being way2old is why I need help from younger minds
