I am wondering how come recently when I pull my car down into gear my rpm's drop to about 200-400??? sometimes it shuts off other times it goes back up to about 600-700..I can normally tell how it starts if it's going to do this? I seem to be having issues with my MAF and I am unsure if this has anything to do with that?

It is often related to MAF or fuel system. Did you buy a MAF yet?

Or clean the MAF connector and tighten the pins?

Very difficult for us to even guess without a maintenance history.

So when was the last time you cleaned your IAC valve? TB? EGR? Plenum? BG44K?
