Can you tell me why my 2001 4Runner hesitates, bucks after a rain fall?
My 2001 4Runner hesitates and drives rough after a rain or when it's humid .....until the engine warms up
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
