    Sounds just like my 09 crd. If you're serviced it and it still lacks power I'd be looking at things such as injectors, rail pressure, boost and perhaps a bad batch of fuel? Could also have the throttle body gunked up if you've run without a catch can for a period of time. Otherwise compression test

    Also if you've just had the floor mats out and when you put them back in the drivers side one folded a little behind the accelerator.

    Happened to my old man, he couldn't overtake anyone for a few days until he figured it out
