Carbahn found a hole in the intake boot and replaced it with the temperamental MAF.
I recently replaced the stock brake lines with SS brake lines and rebuilt of the calipers. Since then the brakes feel spongy to me which is why I brought car to shop. After they bled the brakes there is some improvement to pedal feel but not as good as before. I still think there is still some air in the system. From what I read online it took some people a couple bleeds and time i.e. track days or driving the car before the pedal returned to "normal".
