New plugs were used? Properly gapped?
you installed new wires? And then replaced those? Sure you have the right wires going to the right plugs?
You replaced all 3 coils?
Were the coils new?

Sorry, i wasn't very clear, it only misfired under heavy load 2 weeks ago, now it is constant.
Misfires at idle
Brand new ACDelco professional platinum plugs gaped and checked at .060
New wires( one had a manufacturer defect so i replaced all wires again with a brand new set).
Right wires going to right plugs, carefully followed each wire from coil to plug nothing mixed up.
Installed 3 brand new coils, carefully and correctly re-attached wires, checked them for spark. all working properly.
