Misfire cylinder 1 may include replacing the spark plug on cylinder 1, possibly the spark plug wire, and possibly the coil itself.
This is what I would do. Based on your mileage, if the basic tune up has not been done in the past year, I would start by replacing ALL spark plugs and the wires. Once that is done, reset your computer. If the CEL comes back on AFTER replacing the parts and resetting the computer, and the same code pops up, than you have to replace the coil.
