When I turn on my AC I lose a considerable amount of power. It barely accelerates when I put the tiniest bit of gas. Any other amounts of gas; no speed whatsoever.

 

Sounds like a bad compressor or sensor, would check sensors first. I notice a power loss wile running my AC but if I accelerate hard, passing or playing the AC will kick off when power is needed and come back on when I resume normal driving. Does your AC get cold?

 

It gets extemely cold
