Sluggish When Pedal Is Pressed

[Greg Roan]

I have an 01 mustang v6 it idles great no problem at all. When you get out on the road and get above 1500 rpm it spits and sputters and hesitates really bad. I had it hooked to a computer and no engine codes at all. The check engine light does not come on and the fuel filter has been replaced. I am really stumped on this one could someone give me an idea of where to start checking?

Hard to say what it is. Try putting the pedal to the floor and seeing if it backfires at all. Check your plugs as well for any signs of running rich or lean. Had a similar problem on an old BMW and it turned out to be a faulty MAF sensor
