Year of Manufacture *: 2000
Engine Size and Code *: 2.7 612.963
( Optional) Fault Codes: NONE
Scan of the ECU reveled no fault codes stored so I straight away decided to head for the WPS.
So with the WPS in the exhaust and using a bit of rag to increase the back pressure with a cylinder 1sync i got this.
Now i had a slight issue, as i know with a 4 cylinder you need to ignore the first pulse after your sync and on a 6 cylinder you need to ignore the first 2 pulses after the sync.
So I now produced a misfire on cylinder 4 and from the below capture I could start to work out firing order.
So armed with this info I could now label my original capture.
From here on in the job became simple swapped over numbers 2 and 3 cylinder injectors and retook captures
I was now in a confident position to replace the injector which cured the fault so one final job left was to retake the capture and as you can see all looks good
Regards
Carl
