this is most likely a MAF sensor failure or your evap system has a leak or faulty pump.Check all the evap lines from the tank all the way back to the engine. Most of the time a drop off like this happens its almost always a sensor in the air flow system or vacuum leak in the lines. Go over all the vacum lines under the hood as well.
