My 2000 S-80 has 87,00 miles on it. I purchased it in Oct of 2000 with 18,000 miles on it. The computer was replaced about 2 years later and thats when the problems started. My car was never the same. Now I am having problems with the mass air flow sensor. Every 6 months it needs replaced. Yet when the remove the code from the computer, it runs fine for about 2 weeks. And now it is starting to have electrical issues, in addition to eating head and tail lights.
