Engine Performance problem
1993 Ford Ranger 6 cyl Two Wheel Drive Manual
If I unplug the mass air flow meter the engine will smooth out and run great, but if I reconnect the mass air flow meter it runs very rough and dies. I replaced the mass air flow meter and O2 sensors and still have the same problem. I even tried another mass air flow sensor and the problem continues. It runs very rich with the mass air flow sensor connected.
