ISTA-D correction values?
So I have a low and rough idling N52 and I'm trying to figure out what it is. On ISTA I run the rough running test and idle correction values and these are my results. After I swapped the injectors from Cylinder 5 to Cylinder 4 and cylinder 5 values stayed nicely under 200, but interestingly Cylinder 4 didn't go above 200. Also, in idle speed correction values, it still says cylinder 5 is being corrected. Any guesses?
