A comparison of OBD2 data from an engine running the wrong MAF sensor VS the correct MAF sensor as specified by the vehicle manufacturer.
Long-term and short-term fuel trims are running above 20% and fuel economy is poor.
Engine runs rough at cold startup and sometimes stalls during cold idle.
All the symptoms are off a lean mixture, vacuum air leak or fuel delivery system problem.
But it's just a wrong MAF sensor that fits but isn't calibrated for my vehicle
