Diagnosing vehicles isn`t as simple as plugging using a scan tool, reading codes and replacing parts. It requires a serious understanding on vehicle operation, electrical schematics understanding and the proper equipment to aid in pinpointing the cause of the problem. Case in point, this waveform comes from a 2017 Kia Forte that has had the parts canon fired at it and still has a loss of power, long crank time and also lack of interval oil changes. The middle hump tells the tale. This vehicle has an advanced timing issue that is reflected with the exhaust valve closing early.
