VY V6 2004 commy running rough

[Sammy01]

Hey guys, got a problem with my VY V6 2004 Commy. So pretty much while idling and driving it shakes and feels like it's about to stall but so far it hasnt stalled. While driving its real sluggish and will shake and splutter, it has a delay and wont kick in for a few seconds then will take off and over rev and jump to 5rpm. Almost like it's not giving off any power. The first thing I thought of was the ignition coil packs (I bought a pack of 3 off ebay) so I presumed they were just **** quality and bought brand new ones from repco and spent roughly $50 per coil. Replaced the old ones and it didnt change a thing still doing the same ****. Fuel filter has been replaced as well. Was told it could be O2 censor, spark plugs or ignition leads. Anyone had this problem or know what it is? Pic for attention.

FIRST Get is Scanned,
that will be a good starting point,
Not all DTC's will activate the MIL.

Check your coils and o2 sensors

I know the miss my V6 commy had turned out to be plugs....

It had a rough idle, would miss under acceleration down low to around midrange (2500 to 3000RPM)..

When changing plugs and leads, I noticed the white of a couple of plugs was cracked, which pointed to being the problem
