I’ve had the same problem now for quite some time-probably from around 65k. It normally happens around 2250-2500 rpm and particularly when accelerating lightly after cruising. It’s intermittent rather than regular and doesn’t happen if accelerating heavily. I’ve replaced the MAP sensor and done a few other bits and pieces to gradually eliminate potential causes. Fuel pressure check and replace the fuel filter is next on the list. I’ll let you know how it goes, or let me know if you get there first.
