2003 Nissan Altima Sedan 3.5 SE 4dr Sedan (3.5L 6cyl 4A)
Nice Car, "Service Engine Soon", light came on at 82,000 miles
 I just bought this car used, yesterday and I love it. It is very fun to drive. I traded in a Mercedes Benz 240C, which was powerful, but drove like a tank or a boat. The only issue is that the, "Service Engine Soon", light came on before I even got it home from the used car dealership. I brought it back today and they said it was indicating "High Idle Speed". Well at 82,000 miles I hope that this is all that is wrong with it. I will keep you posted.
