When i start my S13 and it is in park or neutral it revs at 2000 and gradually moves up to around 3000. when i drop it into drive it drops to about 1500.any suggestions?

yes, MAF is mass airflow filter/sensor. I had the same problem and i just cleaned it with some brake cleaner and it improved a bit. Also take your Idle Adjusting Valve off and clean it with carb cleaner, you will have a lot of crap coming out, mine did. Also throttle response improved quite a bit after those procedures.

hope it helps!
