Mountaineer AWD V6-4.0L VIN K Flex Fuel (2003)
ON SOME NEWER MODEL YEAR VEHICLES THE REACTION SPEED OF THE EAC VALVE IS FAST ENOUGH THAT IT MIGHT MAKE
A "POPPING" SOUND AS IT REACTS TO A LARGE IDLE LOAD. THIS IS A NORMAL CHARACTERISTIC AND NO ATTEMPTS
SHOULD BE MADE IN AN EFFORT TO MODIFY THE PERFORMANCE OF THE IAC VALVE. IF POSSIBLE, COMPARE AGAINST A
LIKE VEHICLE.
NOTE
REMEMBER THAT MOST WEATHER SERVICES REPORT A LOCAL BAROMETRIC PRESSURE THAT HAS BEEN CORRECTED TO
SEA LEVEL. THE BARO PID, ON THE OTHER HAND, REPORTS THE ACTUAL BAROMETRIC PRESSURE FOR THE ALTITUDE THE
VEHICLE IS BEING OPERATED IN. LOCAL WEATHER CONDITIONS (HIGH AND LOW PRESSURE AREAS) WILL CHANGE THE
LOCAL BAROMETRIC PRESSURE BY SEVERAL INCHES OF MERCURY (+/- 3 Hz, +/-1 in.Hg.).
NOTE
BARO IS UPDATED ONLY WHEN THE VEHICLE IS AT HIGH THROTTLE OPENINGS. THEREFORE, A VEHICLE, WHICH IS DRIVEN
DOWN FROM A HIGHER ALTITUDE MAY NOT HAVE HAD AN OPPORTUNITY TO UPDATE THE BARO VALUE IN KAM. IF YOU
ARE NOT CONFIDENT THAT BARO HAS BEEN UPDATED, PERFORM THREE OR FOUR HEAVY, SUSTAINED ACCELERATIONS AT
GREATER THAN HALF-THROTTLE TO ALLOW BARO TO UPDATE.
