still struggleing with this misfire

scanned car with code reader, no faults which according to past experience on this forum leads to maf or ignition amplifier. so i un plugg the maf and take down the road, down on power obviously but misfire goes away. so i replace the maf with a genuine item, car ran fine when first set off not even a splutter(engine cold),but as the temp began to rise i got a splutter and then it was back to misfiring again, still showing no fault codes . any ideas??? 99 agu by the way

Somtimes the gauge works fine but it can still be faulty

my car runs fine when engine is cold, but gets worse as it gets warm,some times it will pull all through the revs other times it misfires from 2grand upwards .changed maf and ignition amp for genuine items still no joy, temp guage working fine no engine codes???
