What makes an engine sputter right at the zero spot between accelerating and decelerating? Perfect, steady idle and smooth acceleration, but it sputters/stumbles at all RPM above 1100 or so. It does this with no load (car not moving/operating throttle by hand) and while driving at steady speed. While driving, the slightest bit of light acceleration makes it go away and aggressive acceleration is smooth. It does this in all 5 gears but is more noticeable in lower gears. I'm kind of stumped and it is frustrating to have my car run so well in all other ways, but sputter/surge at steady speeds! I suspect that it isn't helping fuel mileage either.
