The Onboard Diagnostic II system should detect any misfires that occur due to a loss of compression or spark plugs fouled by coolant seeping into a combustion chamber. So if a vehicle has a Check Engine light on and a cylinder misfire code, the spark plug in that cylinder should be removed and inspected for coolant fouling.
