Hi everyone, I'm struggling with my focus at the moment, It feels really sluggish when pulling away, so I have put a EOBD diagnostic machine on to see which codes have come up, The only one is P2008, after some internet research i have came to the conclusion is is something to do with the Intake manifold runner control?! I have asked my local ford parts dealer what it is and he didn't know! The question is, where can I locate this gadget and does anyone know how much it is?

Any help will be appreciated!!!
