Cylinder Misfire

[sharper410]

This is regarding a 2001 base 2.7 Boxster. I got a check engine light warning and clear loss of power one morning. The error code read misfire on cylinder one. My assumption was it is probably a coil pack, but to be sure I swapped the coils between cylinders one and two. I cleared the code and then started her up to see if it threw a code for cylinder two. And of course I got no code and the engine sounds like it is running just fine (I didn't drive it as it was up in the air with the wheel off). The only difference from when I go the code and today is that it is warmer outside now. The wire was still tightly connected before I removed it as I've seen others mention that is a problem. Just seeing if others thought my assumption about the coil is still valid and either the temperature or moving them around made it work again. I don't like throwing parts at a problem and praying so wanted to get other opinions. Your help is appreciated.
