I have had the coils and plugs looked at and been told not them.
Do you know how they tested the coil packs? How old are the plugs (change every 60000 miles ... expensive as there are 8!

Watch backfiring!!! It can and has split the inlet manifold on cars before now ... they are plastic and expensive! Plus running without an airfilter can mess up the MAF as dirt gets stuck to the hotwire.

Have you tried unplugging the MAF when the misfire happens? If it misfires with it and not without, that might be your problem.
