how many miles? Those could do it... do plugs, clean or replace air filter, injector cleaner... fuel filter... just a good tuneup and see what it gets you

could be a MAF or a TP sensor. The only way to really tell is to hook the car up to a computer scanner that can graph the signals from the MAF and the TP.

One way to check if it's possibly the maf, is go under the hood and briefly go from idle to WOT and let off... see how long of a delay and how smoothly it accelerates. If there is a delay or some bogging it coudl easily be the MAF.... try cleaning the MAF those get dirty easy on Fords

i've got 56K on my car. i recently had the fuel injctors cleaned, and i replaced the fuel filter about a week ago. the car only bogs when i've been driving for a while. i'm sure it's something small, but it's annoying. i never know when i hit the gas if i'm going to accelerate, or bog down. if i go with some new plugs, i've heard stock are the best way to go.... true? anyways thanks for the help.

yes get stock OEM plugs. And clean your MAF, it could easily help out.
