Question Re: Welcome to New Members - Post here to say gday!

Hi to all, I'm a proud owner of an 91 EB XR8 , its a great looking car in good condition , however its developed a missfire under cruise and i'm hoping that someone out there might have the answer, here's a run down of what I've done so far to try to fix, Changed plugs, coil, cap & rotor , hallafex pickup , ignition module, oxy sensors , mass air flow meter , TPS ,plenum gasket , fuel pump & filter , replaced all worn looking vac hoses , have sprayed around intake with arostart looking for vac leaks but no luck .
Engine is 5.0 V8 winsor and idles smooth , has heaps of power when under load ,
but misses when cruiseing between 70 & 100 km.
Please can someone tell me whats going on, I'm at my wits end
