On a dry day, take a water bottle with a spray mister on the top and mist down your plug wires, and coils with the engine running. If it bogs down or you hear a snapping sound, you have found the issue.

Yup, sound like you need a tune up. If you have over 100,000 miles on your 4Runner you're overdue for a tune up. HTH. -Jim
