I would also check the spark plugs, and check (and double check) that the sparkplug wire boots are seated properly, and make sure they are seated properly on the coil pack too. Last time I changed the plugs in the Focus (This was around 120,000km's, and the 2nd time I changed them since I had the car), I didn't have the plugs or wires 100% seated and sealed for at least one of the cylinders, and the car can like a bag of crap...almost like it had 3 cylinders, and was slow as hell going down the road. I brought the car home, and went through and pulled and re-inserted each plug and wire in each cylinder going from left to right (when facing the engine bay). This solved the problem, and the car ran like a dream after this...made me happy that I spent the extra cash for Motorcraft Plugs, and FRPP9mm wires again, as the car felt VERY responsive.

I am going to look into doing this with the stang eventually too...run a C&L intake with an SCT tune, etc, and see if the car feels more "drive by wire" like it's supposed to be/have in the first place. Will also give me a boost in fuel economy, and of course, add 30+hp to the wheels. Bringing the car to over 300hp...

Anyways, back on topic...hope what I said about checking the wires and plugs helps with sorting out the car. BTW, when the car hits 80,000 (which it's almost at anyways), I'd reccomend replacing the plugs to Ford Motorcraft ones, and getting her some FRPP 9mm wires (they stand up to cold very well, and heat better than OEM)...the car will thank ya for it!
