My wife has a 400 and when we were on vacation in Wyoming her Fuel Injection light came on. She flagged me down and we decided to stop at the next town that had a Suzuki dealer. When we started back up the light stayed off for the rest of the trip. We decided it might have been a bad batch of gas. However after we got back home (aprox 1100 miles) the light came back on. It seems to be after the tank is about 1/3 empty before it will come on. Has anyone else had this problem?
