My 01 ford expedition xlt 4.6 is acting up when I push the gas the engine revs and acts like it don’t want to go. It will hit 30 and doesn’t want to go. I’ve changed the fuel filter vacuum line ,cat converter , spark plugs I don’t know what else it could be when plugged up to a comp an o2 sensor comes up but that’s it what else could possibly be wrong? Plz help

  1. my initial thought would be the MAF – Mass Air Flow Sensor

    or possibly some sort of vacuum leak.

    Does the rpms go up but doesn’t move? this would indicate a transmission issue, possibly low on fluid.

    Was there any recent work pryer to this condition?
