VZ rough idle fix

[Exidor]

Mine runs rough at idle on occasion.
I cleaned my PCV system (full of gunk) and this only seemed to
worsen the problem. However it now seems have to got better.
I suspect the Alloytec might be sensitive to different fuels.
Was running E10 95 octane. Now standard 91 octane.

ive always run on Vortex 95 i think it is. Only rarely put in anything else when im on empty, and no where near a caltex.

But the few times ive had this rough idle, wasnt at the times i changed the fuel.
