what it could be ? BAD ECU ?

 

Do you have mode 23 enabled?

 

how are you doing the "reading"?

 

What mods did you do before it stopped reading?

 

i had a lot of mods but i tuned the car after all that in its running good ,,, by the days going my idle start acting up and then i changed the down pipe with the test pipe and i used to have an AVC-R i unistalled it but all that work i did it one time ( the down pipe and the test pipe and uninstalled the AVC-R) after that i took it to the tuner and th problem showed up ..

 

So it was tuned with an AVC-R and then you took it off before or after being tuned? Either way I'm thinking thats a good portion of your problem and/or whatever wires you re-spliced from the AVC-R were not done well.
