Air con and reduced acceleration fault

Hi folks

I have a 2005 focus st2. It's giving reduced acceleration fault with fault codes p2122 p2121 which are all throttle pedal position switch d. 

 

I had the instrument cluster fixed and it was still doing it, also cleaned throttle body. I have now found that it's only going in to limp mode with reduced acceleration fault when air con is switched on. If air con is off its fine. 

Has anyone seen this before? 

Thanks

Jay
