Ford Thunderbird Check Engine Light Due to Water and/or Oil in the Spark Plug Tube Causing Engine Misfire

(2 reports)

Water or oil may enter into the ignition coil cover and the spark plug bore, causing a misfire and illuminating the Check Engine Light. A coil with improved water and oil sealing is available and should be installed.

Would a generous amount of RTV work as well to seal up those coil covers? -
