Ford Focus 66KW 2009 loss in power

[Stefanfast]

Hi to all

I need some advices from you guys.

My problems is that my focus experiences a intermittent hesitation in power, even if I'm not forcing it to speed up. It feels like someone push me from behind. I had this problem form the past, but not so strong

 

I haven't found any  check engine light on board, or any trouble code when I've done a normal scan. So I bought a new performanced scanner, I've done a deep scan, and I found 5 trouble codes form the PCM.

P0704-28 - Clutch Switch Input Circuit Fault

P0238-21 - Turbocharger/Supercharger Boost Sensor #A Circuit High

P0407-22 - EGR Sensor #B Circuit Low

P0098-21 - Intake Air Temperature Sensor #2 Circuit High Input

P0488-24 - Intake Throttle Control Position Performance/Range Error

 

Thanks!
