VS rough idle

[Pickled]

G'day, so my VS shakes and vibrates a little in park, when in drive and stopped (at the lights etc) it will idle pretty rough, it will go as low as 400-500rpm. It's on dual fuel also.

Any suggestions on what this could be?

I had a similar problem with mine and it tumed out to be the spark plug leads.
If you have a multi meter that does ohms it wouldnt hurt to check them. Cylinders 1,3 & 5 should have a resistance less than 10,000 ohms and 2,4&6 should be less than 17,000 ohms.
Mine was running terrible at idle and this was all it was. It also wouldnt hurt to check your spark plugs while your at it.

I agree with Shambo check the leads my number 2 lead went also and the same thing happened,and you cant adjust the idle on a vs because it is factory set.

i got the same problem and am hoping its just leads/plugs cause their easy and i know they need doing
and it doesn't bog down like if a coil was dead/dying
