Hj60 1985 random stutter issue while driving HELP (4 Viewers)

Hi Guys,

I could really use your help.
Today while driving, suddenly i had a random stutter in the motor, Felt like it got chocked for a second.

because it stood still for 2.5 months i though maybe some condensation occured in the diesel... Put new diesel, drove fine for about 45 min and it occured again.

i've posted a video below, please help me how i can resolve this, i thought maybe some air in the fuel filter but then i noticed the arm moving on my engine block while running ( see video ) why is it doing it and please advice on how to resolve




Side note engine was slightly warmer then usual

60 series diesel engine stutter - https://au.toyotaownersclub.com/forums/topic/44702-60-series-diesel-engine-stutter/

From what i read in this tread.

i also recently put in a new alternator and new battery...

could it be that voltage is to high or unregular ? and causes the engine to do this?

I wrote a small guide about this issue below.. also given that you recently replaced alternator/battery I'd be double checking that the alternator is actually working and that your main earths from your battery are still firmly attached. A battery voltage measurement under load is the first step.

2H - Engine loses briefly power every 10 seconds or so

Edic (fuel control relay) in passenger footwell probably rusted out , replace with new type, cruiserworld is about two weeks delivery in Netherlands.
Open old box tabs , insert new one and close tabs.

This is also called funky chicken (right?)
Also the oil pressure sensor (not the dash sensor) (located near/under the manual push in fuel pump, the dash oil sensor is on the other side under the alternator/dynamo) can be oxidated and do this (normally stops engine when below 0,3 bar, release oil sensor cable and see, but not to long, replace sensor)
But remove the arm (some sideways force to click/release), remove the edic fuel controller / plug, attach a choke cable to shutoff arm in engine bay and that way you can shutoff from inside.
Glows, starts fine (no over fueling but that is only needed in freezing (also depends on version of superglow/build year)

This small one has a black/yellow wire:

located beneath the starter motor!
