Well, replaced the fuel filter and no joy. Still getting the misfire codes.
I have:
replaced the spark plugs
replaced all coil packs
replaced the CCV system
cleaned the MAF
cleaned the DISA valve
replaced all vacuum lines that I can find
replaced fuel filter.

Also, after the car sits overnight the static fuel pressure bleeds off. Car starts fine, thinking the bleed off is due to the gas cap. What do you think about that?

Any other suggestion for solving this very random misfire events.
