We have a 2003 model vehicle which we hope to replace very soon. The check engine light suddenly came on. We've recently moved to Frederick, and no longer have old friends who we feel we could call on. In addition, I'm the only driver since my wife is recovering from two shoulder replacement operations. One phone call and we were scheduled. The problem was very small air leak, which I was advised to ignore because it is very difficult to diagnose, and the car still runs fine. Thanks for providing transportation from my apartment..
