Vacuum pump, 2.3 ecoturbo charger not available for inspection. Dealer in ND replaced vacuum pump twice and car ran worse than when I brought it in so they then decided it was the turbocharger and replaced it. My check engine light and ABS light were on. Could not drive over 55 mph and was on highway when lost power and slowed way down significantly with traffic congested. Had to pull off to side. Thick Smoking from tailpipe they said oil got lnto the catalytic convertor it would eventually wear off and ok to drive. Took to different dealer and they replaced the vacuum pump again (this was the 3rd one)it has 73000 miles on it. I Drove for 20000 without trouble. Now I’m at dealership in TN and they are replacing the entire engine. Without any help from Lincoln and the car has 91000 miles on it
