Misfire
Steady Misfire
In the case of a steady misfire, isolating the misfiring cylinder is the first step in diagnosing the problem.
Items that can cause a misfire:
Spark Plugs
Coil Packs
Throttle Position Sensore
Lambda Sensor
Head Gasket Failure
A spark plug that shows heavy whitish to brown deposits may indicate a coolant leak either past the head gasket or through a crack in the combustion chamber. This type of problem will only get worse and may soon lead to even greater problems if the leak isn't fixed. Coolant makes a lousy lubricant and can cause ring, cylinder and bearing damage if it gets into a cylinder or the crankcase.
