anyone know if the plug can be replaced? had a look but the wires seem to go to the engine block, like it doesnt look like it can just be unplugged at both ends

disconnecting the air mass meter will screw up idle. it wont hold its own, since it needs very slight adjustments to keep idle between 850 and 1000rpm.

All modern engines have an idle control valve/stepper motor of some description.

I love the guesses people are giving on here!

Yes sam, i was trying to ascertain which one the 12v had, and it turns out to have both which is odd, since they both do the same job.
