Maybe new coils in general ?

Are the plugs dual grounded ? What brand? What brand wires ? Do you have correct firing order ?

Do a compression test on all cylinders !

Are you loosing any coolant ?

i have the napa sparkplug wires so i believe nothing special as far as dual ground.
coolant stays steady no flux.
firin order is matched and nothing has been swapped as i got the misfire 2 stop for a period of time and returned
havent done a compression test have no knock or coolant/oil variance

A compression test, cooling system pressure check, and a check under the valve cover should tell you whats wrong. Unless its an electrical problem.

That would be a last resort after ruling out the others. (broken valve spring, bad cam lobe)

The noid light is a good idea.
