RB20det Xperts needed please

[EVL032]

i have the most annoying problem its an intermittant thing after 5 mins of driving the car will drop a cylinder and then pick it back but again 5mins later.

have had it at other mechanics and htey cant find the fault well they can c it but they claim not enough time to test it.

if any one has had this problem or knows wat it is please advice me. they tested the car with new coil packs ( well 6 of there own) and they say it still does it?

help appreciated as i am all outta ideas
