    MAF P0102 in Aftermarket Intake.

    I wrecked my old Escalade (2004 ESV), and Salvaged the INJEN intake from it, and I noticed that I could just slip it on and replace the stock one my 2007 ESV had. I swapped it out and I put a Breather Filter on the little pipe coming out of the Head (it was plugged into the stock intake, but the 04 intake didnt have a place to insert it at). I placed the MAF Sensor where the old stock MAF Sensor was in the 04 Intake. It drove fine for a couple of days, when suddenly, Traction and Stabilitrak are disabled randomly. I restarted my truck then I notice the Engine Light comes on. Error Codes: C0561, P0102, P0121, P0171, P0174, and P0172 appear. There is a sensor in the front driver caliper (I was told a speed sensor) that was throwing a Code, and also the other codes were showing that the Truck was running Lean, and the MAF Sensor was experiencing an Error. I am putting my Stock intake back on for the time being. Hopefully the codes clear! But any suggestions? As to the MAF Sensor being bad?
