Libertyville Acura Dealer will not help fix car broken down car after having purchaed 2 weeks prior. Libertyville, Illinois

I purchased a used 2000 Acura TL from Libertyville Acura on 12/12/09 on 12/26/09 the check engine light came on I waited until they opened on Monday 12/28/09 and drove my car to Libertyville Acura to see what the problem was. As soon as I entered I was greeted by a young man and I explained that I just purchased this car 2 weeks ago from the dealership and that my check engine light came on already and he replied let me guess you purchased this car from James W. I was about to question that comment because that was the sales man I purchased the car from, when other customers interrupted I figured whatever was wrong could be fixed so I waited in the waiting room from 8:00am until 11:00am for the service writer to tell me it was a fuel injector and 2 ignition coils quoting me $347 and  letting me know he was giving me a better deal since I purchased car two weeks ago I said go ahead with the repairs and continued to sit in the waiting room until 2:00pm when I was told by the service writer and mechanic that there was still a problem and that he could not fix it right away and needed more time I had a ride who I told to leave at 11:OOam so I waited for my boyfriend who picked me up at 5:00pm we had a conflict with the owner Glenn B. who ended up having one of his staff call the police to have meand myboyfriend removed from the premesis.I could not believe the way I was treated after the police wrote the report out we left and I left my car their but came back 1/2 hour later the dealership had pulled the parts out and replaced my old parts I drove in with, now my car did not work at all I had to have it towed the next day to be worked on I was charged $1439.30 for all new fuel injectors and all new ignition coils as well as spark plugs.The car ran for 4 days and now the check engine light is back on car is misfiring still I believe I was sold a bad car and the Libertyville Acura has refused to help me.I can not afford these high repairs I purchased an ACURA because I believed they were reliable and dependable.
