Update: Many of you have sent me PMs, so I thought I would provide an update. I was very impressed with the response from Mazda Corporate. They sent two engineers from Japan to meet at my house and examine the vehicle. As previously mentioned, they also tested gasoline from several...

Ceric - I have the exact same problem described as keith25252 - I'll send you a PM for the same instructions. Thanks.
