Dash Wiring Problems of Mercury Marquis

We bought a used 2003 Mercury gr. Marquis,LS, in Sep't. 2003. Two days later the check engine light came on. The dealer, mace Lincoln Mercury, 629 ohio st. Terre haute, in. 47807, worked on the car 8 times without success. I contacted the Mercury complaint line twice. Scott shepard, the service manager requested a field engineer from the manufacturer. They refused to send one, but told him to install a new computer, which he did on March 26, 2004. The light came on again April 23. I contacted the manufacturer at 16800 executive plaza dr. Pob 6248, dearborn, mi. 48126 April 27, 2004, without receiving a response. But the mace service manager scott shepard, said they contacted him to perform another diagnostic. Mace has had the car for further work from may 4, until today may 10, without being able to repair it. Now, the mr. Shepard calls me and says, he just learned that the manufacturer was aware that all 2003 gr. Marquis were having a problem with this service engine light. They have promised to send a field engineer. The warranty for the car is for 3 years or 36,000 miles. We have 27,000 miles on it. In the 8 months we have had the car, it has been worked on 10 times without success. I cannot get the general manager, terry mace to help me, nor will the manufacturer address me directly. I want another [comparable] car or my money back. I paid $17,700 cash for the car.
