Ok, I replaced the MAF sensor, and still not running right, and still getting error code 0102. MAF sensor reference voltage too low. Here is also another prob. I know the PI intake requires it to be tapped for the second sensor. Mine is not as no one here has a tap for these threads.I have the gauge sensor plugged in, but not the ECU. Now if I plug in the ECU temp sensor and let it hang, the cooling fan never comes on and the idle increases, causing the motor to overheat.
