[AW128i]

Recently, and intermittently, under light to moderate acceleration the engine seems to be pulsing. I can't think of any other way to describe the behavior other than pulsing. It's like I'm pressing on and backing off the accelerator slightly, but I'm not. It's certainly not bad, but it's a relatively new behavior and I can't help but think it's indicative of something bigger. Anyone experience this before? At this point, since it's intermittent and not glaringly obvious when it occurs I know my dealer will just give me the "could not replicate" line.
