Hi to all
I am getting this code for 2 month, and no one can figure it out. I am looking for good mechanic that can realy find the problem .
any suggestion.

1 Fault Found:
17584 - Bank1: O2 (Lambda) Correction Behind Catalyst: Control Limit Reached
P1176 - 35-00 - -

I did check the O2 sensor and it seems to be OK
 
Possible Causes
Intake Air System leaking
Oxygen Sensor(s) and/or Oxygen Sensor Control faulty


Possible Solutions
Check Intake Air System for Leaks (False Air)
Check Oxygen Sensor(s) and/or Oxygen Sensor Control (all of them!)
 
I already fix my intake leak, Could be the MAF or Oxygen sensor and both are expensive so i want to be sure before replacing any part
 
You mean the SAI , Secondray Air Injection, i just changed them, they was Broken. and the pipes between the engine and radiator has been changed too.
 
Thanks for the help, if any one know a good mechanic that can find the problem please let me know
 
it is the the only code i am getting, the car is 100% stock no chip no upgrad.
any ideas, or where i can get diagnostic properly?
thanks folks
