92 lumina Euro 3.4 coil pack

[elcactus]

I have a Lumina Euro 3.4 FWD auto. 30,000 miles. When I first start it up I hear a missfire until it warms up. I replaced the plugs and wires and still the same. My next choice is the coil packs. My question is what is the best way to replace the coil packs. I know it was a bear to get the wires on and off. Any help would be appreciated.

Thanks, Jody
