I have a nice 2004 Ram 2500 5.7 120K miles on it, which I only use for towing my 24ft trailer. Are these 5.7 Hemi's prone on having bad O2 sensors. The check engine light always on. I have changed Senors a few years ago. That only worked for a short time. Is something messing up my senors. I just changed the Spark plugs today. The right bank look great maybe a little lean, the left bank are running rich. The gas mileage is down a bit also.
About 7.5 miles to the gallon with the trailer and Cuda.
Anyone have troubles with this before
