relatively new E-350 has mysterious problem..
I just had the mass airflow sensor replaced on my van because it was having a problem where it woudl start for about 1 second and then die. It then worked great for about 2000 miles (out to the East Coast and back home to Chicago). Last week it broke down after about 20 miles on the highway. It just stopped accelerating, I pulled over, and it died as soon as I stopped it. Then I was unable to start it up.
I left it at the auto shop, and 3 days later they say it started up again just fine. Did I buy a lemon? This thing has 65,000 miles on it, it's a 2006... it shouldn't have any serious problems. Anyone have an idea of what the cause might be for randomly breaking down, being unable to start, and then starting back up fine 3 days later??
