2007 vectra 1.9 diesel. Misfire on cylinder 1, misfire jumps between cylinders, replaced injector but problem still persists. Checked wiring and all 4 injectors have a feed.

All 4 injectors are getting fuel, swapped injectors round but still misfiring on cylinder 1.

timing on crankshaft was out by 2 teeth, set timing properly with new belt kit, checked keyway and all ok.

possible bent valves? Stumped on this one. Verus scanner comes up with no codes untill you unplug injectors so wiring between injectors and ECU is ok.

I think there have been loom faults with injector 3, hope you have put injectors back in their right places, they are calibrated individually. ECU is programmed to allow for the differences.
I don't know what the cause is, I wonder if EGR is leaking? May be worth temporarily blocking it to see if it affects idle etc (it will bring on an EML) but should run properly.
