Hello, thanks for using 2CarPros. Com. Is the check engine light on? And yes heavy rain can cause issues if you have spark plug boots or wires that are deteriorating, electricity and water do not mix. But a scan of the ECM (engine computer) may give some data as to what is going on. Your locale auto parts store should be able to scan the ECM for free and see if there are any codes or useful data.
