I finally got her into the dealership and the tech tells me that my MAF is bad. They want $390 for a new MAF, reprogram PCM, and installation. I know that for a little of 200$ I can get a 75mm MAF and have it programmed for much cheaper. What exactly is my PCM and what does it do? I still have my BAT intake and would love to re-install it, but now I am worried about more problems with the damn thing...
