Re: Acceleration issue

This fits better in the 96-04 section vs. the 2011 section...

Anyway,have you noticed any other symptoms (mis-fire, bad vibrations, odd idle, etc.)? As Kultulz says, a scan tool helps narrow things down quite a bit. My best guess though would be plugs (mine died well before 100k so if you got some miles on yours, this is a good start), bad O2 sensor (if you replace it, get Motorcraft only as Ford plays some games with them), or a dirty MAF (especially if you have a K&N filter). Less likely but also possible are a bad FPR, coil(s), sticky EGR valve or a bad DPFE sensor. A vacuum look could also be very possible. As you can see, a scan tool can help narrow things down a bit.
