I just pulled the codes on my 96 F150 XLT 302 4x4 and got back 0411 and 1359? Any help to fix these would be awesome! On the 1359 I did the timing advance upgrade with everything recomended MSD wires, cap, and rotor, and motocraft spark plugs gapped at .56, I checked the timing with my code reader and it was at 17.5 but code 1359 was not showing at that time, it is when I backed the timing off to 13.5 that code 1359 came on. HELP PLEASE!

 

Code P1359---Spark Output Circuit Fault-02

Code P0411---Secondary Air Injection System Incorrect Flow Detected

Any one with any idea on where to start with these codes?
