AEM FIC fight for turbo!!! - Toyota Yaris Forums

So after unplugging my FIC and starting the car it immediately gave me a few dtcs. I got Maf circuit too low, and a few misfire codes. Bad Maf sensor? I may have a shop test my sensor to see if it's bad or something. Is the MAF circuit too low a hint to anything regarding my stalling out? I'm pretty sure it's misfiring all the time but it only gives me that code when I unplug the FIC and hook in the bypass. Checked my plugs and I have some pics of them. Wanted to see if anyone thought they looked anything but normal. I need to figure out this misfiring issue.

Can't upload them straight from my phone because the image size is too big I guess. I'll post a link to them when I get a chance.

Make sure your grounds are clean and tight. And check for corrosion and loose connections.
