Rough lumpy idle VR6

[karjadi15]

Ok so I need people's expertise here. I have changed the spark plug, i have got brand new ignition leads. The MAF is clean, the throttle body is schmick clean. The coolant sensor is also cleaned.
Yet the idle on the car is still rough and a bit lumpy.
As most online have suggested I did the Epoxy method on the coilpack. Its all good but when I turn the car on let it run and spray water on the coilpack region it gives off a spark. I have sealed all cracks as well.

Any ideas guys?

Thanks in advance

Be careful when you clean maf or air flow sensors, they are very sensitive.

From memory the Vr6 has a main engine loom with a round connector. Heaps of wires going through it. Located near the engine? My old Vr6 had a miss and it turned out to be a broken wire to that particular connector

if coilpack is sparking then it's definitely time for a new one.

It was cracked a bit only thats why I decided to do the whole epoxy method thing. But yeh still sparking, which is annoying only on one of the plug though, cylinder 6
