Thats what I would do. Im also wondering if you have a leak somewhere or a pump thats dying and rail pressure is dropping until it builds back up. Does it have trouble starting on the first try?
Yep! I'll be clearing adaptations today to see if it helps. i dont see any leak in the engine bay tho. My mechanic suspects O2 sensors are the cause (since im running catless downpipe) and he's gonna put on O2 bypass today. I'll be updating this later
