Summary
"SITUATION: WHILE DRIVING IN WET WEATHER CONDITIONS, CONDENSATION MAY BUILD UP WITHIN THE ENGINE CHARGE AIR RADIATOR. FOLLOWING A RAPID INCREASE IN ENGINE SPEED, THIS CONDENSATION COULD BE DRAWN IN TO ONE OF THE ENGINEÂ’S CYLINDERS, CAUSING THE ENGINE MANAGEMENT SYSTEM TO SENSE A MISFIRE. THE ENGINE IS PROGRAMMED TO REACT TO THIS MISFIRE BY INITIATING A RESTRICTED PERFORMANCE MODE TO PROTECT THE EXHAUST CATALYST. IN THIS MODE, THE DRIVER NOTICEABLY EXPERIENCES REDUCED POWER TO ACCELERATE UNTIL THE ENGINE IS SWITCHED OFF AND THEN RESTARTED. FURTHERMORE, AN ENGINE WARNING MESSAGE WILL DISPLAY IN THE INSTRUMENT CLUSTER MESSAGE CENTER AND THE ENGINE MALFUNCTION INDICATOR LAMP MAY ILLUMINATE."
