Extreme Missfire R32 Gtr

[xtermin8or]

Hey guys,

Engine started misfiring randomly some time ago, thought it might of been the plugs, so i changed them with normal copper ngk plugs. Tested afterwards and same problem.

It starts off normal , then a bit of misfiring until it sounds like a tractor and goes nowhere..

I then replaced my Split fire coil packs with new ones i just bought. - Same thing, just takes a little longer to get there.

I really dont want to miss out on Winton on 9th OCT. Any one got any ideas what it might be??

Car has the standard boost restrictor taken out, so im running pretty much the full bar, and i was told the plugs were gapped @ .8 (My friend had the same issue and got his plugs regapped and problem went away)

Also is there a way of testing out the ignitor/is that prone to failing ?

Thanks

make sure all the coilpack plugs are in properly

Original Air Flow Meter? Might have done its days. I had the same issue years back.

Wish you all the best with it, as mine wasn't a simple fix.

Thanks mate, anyway to check if the AFM's are fckuced? Or should i just give them a clean and see what happens?

And yeh the coil packs are in allright. The engine all works fine , untill it heats up a bit . Probably 20 minutes of driving from start.
