Q: Car runs rough in rain or humidity

asked by on February 05, 2016

My car runs rough, especially when it's raining or humid.

If your car is running rough under wet or humid conditions, this may be indicative of a problem with the vehicle’s mass airflow sensor, or perhaps one or more of the ignition coils. As these problems are electrical in nature, I would recommend having the vehicle’s electrical system inspected by a professional technician, such as one from YourMechanic, to determine the exact nature of the problem.
