Ahhh, a fellow Cedar Rapidian!

Did you happen to notice if cylinders 1 and 3 happen to share a coil? If you have an inductive probe for plug wires you could measure the voltage on the plug wires to see if in fact the spark is weaker to those two cylinders. You also could check those two plugs to see if they look like they've been firing.

Before buying a new coil you could also swap the plugs with some other cylinders to see if the misfire code follows the plugs, swap around wires to see if the codes follow the wires, and maybe even swap coils to see if the weak spark follows the coil.
