VS commodore missfire underload?

[boostin94]

Okay so recently my car developed a miss under load, it was fine if you drove like an absolute grandma but as soon as you gave it anymore then a quarter throtal it would start spluttering and running like an sack of ****. I changed the spark plug leads and spark plugs but the problem persisted, but when i cleaned the throtal body it almost completely fixed it, now its just an odd little miss under load every now and then. still pisses me off though, any ideas?

thanks Scott

I've just fixed this problem with my VS Statesman.

I started with the easy stuff first and bought new spark plugs and leads. If that didn't fix it i was expecting a fault in a coil. Luckily it was in the plugs and leads.
I hope i'm not just stating the obvious - Good luck!

Yeah thats exactly what i was expecting, but when i cleaned the throtal body it helped alot so im confused
