check for moisture under the dist cap and wipe it out. Try spraying a bit of WD40 inside and clean contacts with fine sandpaper or something of that nature. Is the cap cracked? Check it closely, as hairline cracks have been known to cause this sort of problem. If the car is not realtively new and has 50,000 or more miles on it, just try replacing the cap and rotor. They are usually cheap, and are usually an item of neglect by most owners. good luck your spark plug wires are probabley leaking when damp you can check this when the car is dry by spayind a mist of water on them when engine is running use an old windex sprayer or such if the wires are bad the engine will do what it does when it is raining

Will a weak cdi unit cause an engine to idle rough?
Yes, a weak CDI (Capacitor Discharge Ignition) unit can cause an engine to idle roughly. The CDI is responsible for delivering the spark to the engine's ignition system, and if it is malfunctioning or providing inconsistent spark, it can lead to poor combustion. This results in uneven engine performance, including rough idling. Other factors may also contribute to rough idling, but a faulty CDI is a common culprit.

If there are additional problems with the fuel system or air intake, those could lead to rough idling or stalling. It's advisable to have the vehicle diagnosed by a professional to pinpoint the exact cause of the idling issue.
