The sulfur-containing fuel turns into hydrogen sulfide. Cylinder 1 and 3 fire at the same time (only one has compression at a time) from the same side of the coil. It is likely that the coil is going bad. Mist some water at the coil in a low light garage while the engine is running and look for sparks. Also mist the wires from the coil to the heads looking for sparks along the wires.Excessive catalyst temperature can also be caused by cylinder misfire, which continuously flows unburnt HC combined with oxygen to the hot catalyst, burning in the catalyst and increasing its temperature. [22] Unwanted reactions [ edit] Unwanted reactions result in the formation of hydrogen sulfide and ammonia, which poison catalysts.Mark the #4,switch the coil packs,then clear the code. If the DTC comes back as the #2 cylinder this time its the coil pack. If it still comes back as the #4 cylinder then it might be a clogged/dirty injector.
