Ranger 2.2 Endles problems

My Car was to ford dealers back an forward with endless problems, this is the second time the boost pipe leaves me and my family next to the road while travelling further than 100km form home. Yesterday we sat next to the road for 3 hours in a secluded area and my family was stressed and in tears.<br> <br> Is this how ford customer cares deal with all their complainants..... My car went in for a service the Th of this month, a very helpful Marilette helped me with the service and all went well and the performance and lag issues were resolved. the day i went to fetch the car it drove like a brand new model and the fuel consumption was perfect averaging 5.7 to about 7.8 and wasn't smoking at all with the best performance it ever had. The next morning upon starting the car it was back to it old self averaging 11.5 to 12.8 with smoking and medium performance. I phoned Marilette and the reply was i need to drive the car 4-5 times and the computer will settle and be back to normal..... Well its been 15 time already and still its not performing and is very heavy on diesel....I phoned again and she said well i can bring in the car and they will reset the computer again ......
