S13 Mafs

[Nitrus0nous]

From piecing things together from reading different posts, I've come to the conclusion that my MAFS is going bad. From time to time, when accelerating, my car seems to stutter a bit. It also happens somewhere between 2500-3000 rpms. It has done this for awhile, even after the new engine. Yesterday it stalled on me for the first time since the new install, and then 2 times afterwards within an hour. Then I got home, parked it, went out later....no stalling, minimal stuttering. ANYWAY

What's the price for a new MAFS? And would i be able to get it from somewhgere like Advance Auto?
