After I change the plugs and wires, what other adjustments do I have to make?

The plugs and wires are very important to your engine performance. Is this the first plug and wire change? Did you just buy this vehicle used, or are you the first owner? What is the mileage? How is the vehicle running at idle, smooth, shakey, or dies out? If you dont have the small owners manual, then to be sure that you are doing the recommended services to this vehicle, (at the right time intervals) maybe the dealership will be able to tell or email you the maintence schedule. Plugs and wires are a major part of a tune up, but with vehicles being very high tech, in some cases other checks may be needed, visual or computer testing. Is there a check engine light on? Before doing the tune up be sure to visually check the old wires before discarding them, for cracks,rubber insulation wear,and broken wires(dangerous use caution).Spark plugs also need visual inspection for excessive wear, carbon build up, broken part, oily or fuel soaked. These checks also let you know some important things that are going on inside, and outside of your vehicle.The back in the day tune ups required a bit more than todays vehicles. Todays ,manufactures give in some cases up to 100,000 miles before the the first tune up. so check the maintence schedule,and do extensive visual checks of these area, always use caution: air filter, PCV valve, any leaks or fluids that may need changing,any other problems or strange smells should be taken care of immediately, and there are more checks, so maintence schedule to be sure, and visual checks.
