welcome in here.

I am sure people here will be able to help you with your focus.

I would look into getting the DPFE and EGR valve checked. those are both sensors that are relied with exaust gas recirculation for better air and gas mileage and happen to both kinda act in the rpm range you are talking about. If everything is fine with those, have the fuel pump checked, I and lots of other poeples have had their fuel pump go bad and it can somehow start with hesitation symptomes.

so parts to remember with focuses are:

DPFE sensor (fluctuations and surging and stumble)
EGR valve (never personaly had this one, removed all on my last car)
Fuel Pump (stumbles, hesitation, no power)
Sway bar link (go pop when going slowly over bump)
Ignition barrel (key cant be removed)
TPS (throttle position sensor) can be fooled sometime and act with throttle related symptoms.
All AC compressor I saw were leaking after a year


any other parts guys???


thats the roll call, but might as well tell you from the get go, I still love my focus and I would buy it again, but it sure help to know there common faillures so you can keep an eye on thoses.
