2020 Ranger XLT 2WD misfires

[Rangoon]

Problem occurred around 30,000 miles. The misfires began when driving uphill on a local freeway. Later, at home, ran a scan and found cylinder 3 was the culprit. With low mileage, expected the sparkplugs to be okay but more likely a coil going bad. Was going to swap coils between cylinders 2 & 3 to diagnose. When pulling the coils discovered water pooled around the coil boots but only on cylinders 2 & 3. Blew out the water with compressed air and cleaned the coil boots with electronic parts cleaner. Swapped around the coils and since then no more misfires. Has anyone else had a similar issue?

Some have had rain water leak from the cowl onto the engine and get into the spark plug wells causing the exact problem that you are having. see this thread:

Thank you for letting me know that my misfire is not unique.
