Have anybody else had the "service engine soon" light on? Well, I had mine on for a while today. I read the manual and it seems like it's nothing big as long as it's not blinking. The thing is, I had about 3 quarters tank left, and well, seems like there's nothing wrong with the fuel cap. But well, just seeing if anybody else has this problem, I'll prolly bring it to the dealership in the next few days if it doesn't come off. oh ya, I have a 2001 Sentra GXE.. by the way, I've heard there's lots of problems with Nissan's fuel gauge and so on, even on previous cars.
