When you gut the mass air sensor.. which means cutting out the aluminum piece in the middle. Be sure to take that back plate off.. I didn't have a tamper proof torx bit to take it off so I just cut down the middle of the plate leaving a piece connected to the shaft. I proceeded to turn on my car, note the battery had been disconnected for 2 hours and it idled rough and everything.. then after about 10 minutes it was dumping fuel.. so I was like wtf, check engine light and everything. I pretty much knew what the problem was. I proceeded to buy a good set of torx bits, got home, and removed the remaining piece of metal plate, put it all back in place started it up.. little rought idle, then a peaceful idle ! I figure the sensor was either sensing too much air or not enough air (Because of the plate). So everything is good now.. I can feel a few more horses and the car runs cooler than it used to (which was really cool). I also got my home made cold air installed Moral of the story ?
