Just normal corrections on this car....it happens all the time bc our DME is overly sensitive/knock sensors sense some knock...

If the timing pulls are very consistent and persistent in that specific cylinder then you definitely have an issue...

I attached a picture of an excel datalog that has no corrections in 5 cylinders but 1 cylinder is making some noise....but nothing to be worries about unless it happens in the same cylinder in ALL logs...then you got other problems...So just do some more logging and make sure its not always there and you are alright....any corrections with bigger increments than -3 or so id pay close attention to
