I had a similar problem and it was the mass air flow sensor. Don't go to the dealer, they will charge you 400.00 for a 60.00 part.AnswerIf the MAF is At Fault, sometimes the wires inside are dirty. I sprayed the heck out of mine with carb spray and then dried it out in the sun for 2 hours before reinstalling. You can use a simple digital volt ohm meter (DC volts between A&B should be 10 or more while running (mine was 13.something).
Between C & D, the DC volts should be somewhere above zero (like .35) but under 2 (mine was .86).
I think this voltage range means the MAF is OK.
One more possible thing - my kid's 4.6 sputtered under load and idle fluctuated between 800 and 500 rpm. It was a bad wire. When we pulled it off, the connector stayed on the plug. New wires cured everything.
unplug meter while running if condition improves clean or replace meter
check the recalls!!
The most likely cause is a dirty fuel filter that starves the engine.
