forgive me if someone posted a similar question but I hadn't seen one. I have an '04 Cayenne V6. Recently, when I brake and then resume speed, I feel a pause or a hitch in the acceleration. I haven't experienced it before; it's like a small "pop" then the car resumes. It doesn't happen when I brake completely, only when I slow down and then speed up again. Anyone have a similar experience or possibly know what could be causing this? Any info would help. Thanks all.
