VR 5.0L missing

[hkmonaro]

Gday all,

I have a vr5l that gets a miss in it pretty much as soon as the engine gets warm, i have replaced all the normal stuff such as plugs, leads, dizzy etc which has helped but def not fixed the problem, i am guessing that it is developing a leak from a head as it gets hot and then affecting the firing somehow? Its the only thing i can come up with because it seems to only happen after about 15-20 mins so i dont think its fuel either? Any ideas?

Thanks in advance!

I did the check just got 12flash for nothing wrong, mind you i did it when the car was relatively cold, after checking plugs etc
