I have Sentra 200SX, 1.6, 1997. It has almost 99 000 miles on. Recently the light "Service engine soon" turned on and wouldn't turn off. The performance of the engine didn't change at all, though. Can anyone tell what the cause might be? Thanks

If you're not too mechanically challenged you can read this:

otherwise get it checked out at the shop or dealership soon like it says
