There are dozens of things that SES could be for. You'll need to get it scanned to figure that part out. If you don't have access to an OBD scanner, any local Autozone will do it for you.

What’s the worst ting it could be?
car is running the same way it did with no light on

like RPM WS6 explained, it could be soo many different things. most likely a bad sensor, or something small like that. take it down to advanced, NAPA, etc. and have them scan it, then tell us what the code is.

ok i got it scanned the code is p1133
the guy told me he check on his computer and it said
insufficent switching sensor 1/bank 1 fuel control shifted lean so.
i wanted know if it can be fixed with tuner or maybe sensor or
is it mechanical ............................................anyone know?

Sounds like you have an O2 sensor thats going bad. Bank 1 should be the driver side exhaust manifold primary sensor, meaning the one before the cat. Also referred to as the "Upstream" sensor. They are about $79 at any auto parts store. I'd swap it out, reset the ECU, and see if it solves the problem.

Hey i just had the same damn problem about an hour ago. I almost made it home when the damn SES light came on.

its from your o2s. like posted above long tube headers will cause this problem, since the o2 sensors do not heat up as much as with the stock headers causing the o2 to read incorrectly and the code to pop up. i would clear the code for now, and see if it comes back on. if so id try the bosch o2s. the part number is 13111. they have higher wattage heaters to prevent this problem from happening.
