Ve V6 2008 miner misfire/ chucking under accelaration

[Trevor loves holden.]

I'd be looking at the injectors. Cats work by heat but get them to hot and they can melt the guts out of em. The PCM monitors how the cats are working via the O2 sensors. Seeing as you have covered the ignition system fairly well the most likely issue is on the fuel side. A clogged or leaking injector could well be the cause.

A simple test would be to swap the injectors over to the other bank and then see if the fault moves with them.

Not reading any faults, probably needs to plug it in and see which bank is playing up. My car is alloy Tec it has plug leads lol. Should of said VE. Anyway good luck with it.

Thanks mate, but that’s the problem their are no error codes specific to either bank, the only code that comes up is the cat code for both sides

Ok, I thought the problem was on one bank. Have you tried cleaning the MAF?

That's a good Idea but the trouble is its a pain to get that top manifold off every time you want to get at the injectors. At least the latest top to bottom Manifold gaskets are ORINGS not paper/cardboard and glued in like my one was. F!@#$%^&*k

Ever work this out? No end.... was it the injectors in the end....
