Yup thats what she does. Im pretty sure it isnt the engine but a sensor pharaps. altho i changed both o2 sensors an plug it still does it. When I boot it also she backfires an pisses and farts around.

Holden want $140 too find out what the problem is and thats just for the 1st HR then what ever after that. They can go jam it fair up there arses is pretty much what I told em. I know how it works and it wont take even 1 hr too tell me whats wrong by pluging a Dignostic tool into it.

I said what it dont even take an hr too pull the coed out and she said oh oh I'll have to make sure I'll go ask some1, I said nah cya

When it is idling, pull each lead off and see which one doesn't make a difference. Sounds like a failed plug.

.... you already changed the plugs, as previously noted, but have you tested your leads?
at the least, run a multimeter over them, and check the resistance - the longer they are the higher the resistance obviously, actual specs. will be in your workshop manual. also try gently flexing (not tying in knots) the lead as you check it as well.

..always check the cheap things before replacing the expensive things!

O2 sensors i reckon,get the Bosch ones they r better than what holden uses(AC DELCO)I had mine replaced with acs' and didnt last too long swapped to the bosch ones and all good.
repco workshop here charges 70 for a scan,do you have a repco or similar neer by,Holden r always expensive IMO.

Changed the leads to 9mm an lol its fine now. I feel like a idot coz i should have changed them long ago
