If you go to autozone they can read your code for free and reset it for you.

 

"i did clean the o2 sensors the other day wonder if its that..anyone how do i reset the computer just unplug it from battery for a bit "

How did you clean your O2 Sensors?
I have heard that it is impossible.
I might have to experiment with some brake cleaner next time I have to swap one out.
That could be the source of you CEL.

Unhooking the negative terminal for a few minutes will clear any trouble codes.
You can always use that time to clean the terminals.

I would pull the codes first though.
Many auto parts places will do that for free.

 

Try this: Check codes

 

i just took both sensors out and used carb cleaner and a toothbrush soaked em for a bit and put them back in no problems for 2000 miles now, they do have little holes on them that the fluid can penetrate...
