Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here. The code P1131 indicates a lean condition on bank one and the code P1506 indicates the Idle air control solenoid is unable to control the idle speed. The first thing I would be looking for for these codes is an engine vacuum leak around the intake area. Try removing the intake hose from the throttle body and placing your hands over the inlets and see if the engine stalls out as it should. If it dose not then you have a leak. Check this for me and let em know the results.
Okay then I would suspect if you are sure you have no vacuum leaks then you could have a bad bank one HO2S sensor . Is the engine idling high?
I can send you the steps to diagnose these codes from the service manual if you would like.
Got it. Thanks.
Did you get the manuals?
