mass airflow help, please???
i have a 2001 V-6 3.0 ranger and i am running rich. i can smell the fuel in the exhaust and i am sputtering at low rpms. i was told that the MAF could need cleaned or replaced and that could cause me to run rich. i was wondering if anyone else could confirm or has any other ideas as to what would cause this. my gas mileage has been lowered very noticeably. i recently changed the plugs, wires, air filter. the engine is firing properly (no codes except an old one for emissions?) all things were changed after the problem started. i went from getting just over 300 miles per tank to about 180-200 so a pretty drastic drop in MPG, i thought.
