It should be a straight-forward removal and replacement, and not too hard to find or get to.

Your best bet is to go out and grab a Hayne's Manual for your car. You can get them at any autoparts store and they cover specific model/make/year of each car they disassemble and put back together---that's how they write the book and get so many pictures. They cost about $20, but you get that back in less than an hour if you do the work yourself by saving on labor costs.

A mass airflow sensor for your stock Hitachi throttle body costs between $127. - $165.00 You'll need a set of tamper-proof torx sockets from Carquest to remove and replace the mass air flow sensor on the front side of the throttle body intake.
