Two things ...im driving a 97 a4 1.8t quattro and i have a couple codes and im not really sure what i need to fix P1136 something to do with air fuel and P1559 something about idle speed and i have the haynes manual for my car and it doesnt give me a fusebox layout and mine was ripped out of my manual that came with the car anyone know where i can get that ??? thanx

 

P1559 = throttle control unit - basic setting malfunction problem was accelerator pedal or starter motor operated during basic setting,

P1136 = long term fuel trim, idling, bank 1 - system too lean problem could have been caused by the other code or there is an air leak in the vacuum system or AIR system

 

I would look for a vacuum leak. Sometimes if the leak is big enough it will throw a code for the throttle because the throttle can not compensate for the air leak. Just check all of the vac lines and breather lines for leaks.
