My 07 Chevy Malibu with 3.5 L engine runs fine, but when accelerating sometimes sounds like trickling or running water when accelerating. Especially noticeable when accelerating slowly, after being in stop / go traffic. Any idea what this could it be? Has done this for at least the last 40,000 miles or so. If powertrain problem, I have warranty for another 7,000 miles.
