Nissan Micra with Faulty Injector Driver Waveform Notes

The above waveform shows a Nissan Micra with a faulty injector: the injector driver for cylinder number 4 was found to be faulty which meant the injector was not opening.

In this waveform the FirstLook sensor is in the exhaust and it shows a big difference in exhaust pressure between cylinders 3 and 2 as there is no combustion taking place in cylinder 4. Firing order is 1342. The blue trace shows ignition on cylinder 1 (when cylinder 1 is firing cylinder 4 is on its exhaust stroke).
