missing under load

[vsII manual]

Title says it all.
I have changed the plugs and leads but still does it. Only seems to do it when it is at operating temperature though and under load? Its quiet annoying. I noticed it when i had to over take some cars on the freeway in 3rd doing about 160 the weekend on the freeway, and also around down doing about 60 in 4th and flooring it without changing down a gear.
Do the coil packs stuff up on the v6's much? This is all i think it could be as it only does it under load.
Any ideas?

Coil packs on the v6 Commodores are pretty notorious...check your injectors too.

Agree...I had all three go on my old VP...not too expensive...I think about $100 each..easy to fit too!

if you just replace each coil its 50 dollars per coil, if you replace the whoel coil pack its liek 250 bux
