P1103 - This error occurs when the measured value of mass air flow is higher than a threshold value for a predetermined period of time.

According to what I have it could be wiring, MAF assembly, or the PCM

The AFE and the lack of tuning for it will cause that code. What altitude are you at?

hmmmm, I have fixed that code for a couple other guys, and will gladly fix it for you. Depending on Temperature, tuning, elevation, and brand of air intake it can throw this code.

Give me til this afternoon, i'll have an update on the web!
