So it started when I gave it more throttle for a while. But the problem is still present. It cuts out when idling but fine when you give it a little more rpm.
Took a video of the fuel pressure regulator. Maybe you know if it’s suppose to sound like this?

Just had the shop plug in a diagnostic computer and run some tests. They were going back and forth with some experts and came up with a theory. Faulty alternator which messed up the crankshaft signal.
So they disconnected the alternator belt and voila, the idling problem went away.
However, the crankshaft signal is still not perfect..

You could try the earth connection between the battery and the chassis and engine/gearbox.

Otherwise it can be the sensor or the cable to it, both are known to give problems. Roel

Thanks Roel,
I had a good look at the earth connections and give them a polish. But they were looking pretty good, so I don't think that's the problem.

I also got a new alternator and mounted it. Fingers crossed now, but I think that solved the problem! Haven't experienced any issues so far at least. I'll still swap the crankshaft sensor when it arrives.

Thank you all for investing your time in this! It means the world to a novice like myself

You can get a lot problems with variable reluctance sensor ( crankshaft sensor ) i.e. wire coil wand around magnet. if screen wire is damage and or not air gap correct or metal swarf on end the sensor
