misfire?
So ive been reading thread after thread about misfires. The lower rpm shudder and gets better when O.D. button is off. no codes no check engine light. the coils where changed aswell as the spark plugs a while ago. i checked them and they seem to be working properly. so what are my other options as far as what could be wrong.

Most of the time misfires will not cause a CEL. It takes a lot of misfires in a given period to cause the CEL to come on.
If you do have a misfire, a code scanner that reads pending codes will point you in the right direction.
