My check engine light came on so i got the codes read.

P1136, Long term fuel trim add. Fuel B1 system too lean.

P1565, Idle speed control throttle position lower limit not obtained.

Now what do I do to fix them?

Vac leak?

I still haven't found the issue. Talk about a thread from the dead. The engine is AEB and i replaced the two vacuum lines that i could find and cleaned the throttle body. But still have a Check Engine. I'm going to have to get it read again and see if its the same.
