Has anyone cleaned the throttle body yet?

I have cleaned the throttle and was fine until yesterday when the light came back on. I did fill up my gas tank but drove it about an hour before the light came on. I am confused. What do you think would be causing the light to come on?

I think they have problems with the connector at the throttle body if i remember correctly!

you may have to remove the throttle body to do a thorough cleaning.also a dirty or clogged air filter could cause this code to.
