LINCOLN 2009/2010 THROTTLES DOWN WHEN A/C ENGAGES. AFTER 1 YEAR OF REPLACEMENT OF PARTS. INCLUDING A/C COMPRESSOR. MASS AIR FLOW SENSOR. THROTTLE SYSTEM. CAR REPLACED 1&1/2 LATER WITH 2010. AT FIRST USE OF A/C 2010 CAR THROTTLED DOWN CAUSING IT TO JERK..REPORTED TO SERVICE MANAGER WHO STATED WITHOUT INSPECTION IT WAS A CHARACTERISTIC OF THE CAR. I REQUESTED A FIELD ENGINEER TO INSPECT. CAR INSPECTED AND 2010 MKS DID THROTTLE DOWN 50-70 RPM . THE CAR THROTTLES DOWN GOING DOWN THE ROAD. ENGINEER STATED HE WOULD REPLACE MASS AIR FLOW SENSOR AT 1ST SERVICE OF CAR ON5/28/10. WHEN I CALLED TO SCHEDULE SERVICE ,SERVICE MANAGER STATED HE RECEIVED REPORT AND MATTER CLOSED IT WAS A CHARACTER OF THE CAR. THERE IS AN ELECTRONIC PROBLEM THAT CAUSES THE MKS TO THROTTLE DOWN WHEN DRIVING DOWN THE ROAD. THAT IS A POSSIBLE SAFETY CONCERN FOR ANYONE. NOTE THIS PROBLEM IS NOT AS BAD AS THE 2009 I HAD AS IT SHOOK EVEN AT IDLE. I BELIEVE FORD/LINCOLN MKS HAS AN ELECTRONIC MANUFACTURES DEFECT. SOMEONE NEEDS TO HAVE FORD CORRECT THIS PROBLEM AND HAVE THEM ACKNOWLEDGE THE PROBLEM. IF THE ELECTRONIC PROBLEM CONTINUES AS WITH THE PREVIOUS MKS THE PROBLEM INCREASES SUGGESTING COMPUTER DEGRADATION. *TR
