Hey Scotty,
Just bought a 2010 Toyota Corolla with 77K miles on it and am looking to replace the spark plugs because they've been in over 10 years. Do I need to replace the ignition coils as well? There are no issues with either currently.

Unless a coil is malfunctioning I wouldn't replace it, one or 4. Spark plugs do wear and can get dirty, they should be changed.
