No, there are no adjustments to be made if you are just repalcing the coil pack. By the way, how come you are replacing it? Are you doingt the wires at the same time, you should if you are over 50,000 miles on the factory wires. If you replace them go to 8mm. wires like Magnacor's, you'll get alot better plug spark.
