My fuel mileage has dropped from 25.9 to 17.9 in a very short time, I have a code from the obd2 which says lean upon accelleration I believe it is p1170. I replaced the fuel filter and the air filter also the spark plugs, the motor runs fine but the tail pipe is very black and the exhaust smells rich also the engine temp is normal. Thanx Pat.
have the same problem?
