So when I drive, the car runs fine as long as I don't let it drop to idle. When I start it up it idles just fine. But after I take it out it idles drops to about 500 then dies. The cars running a little rich but ive got no clue why its dieing.

Clean your MAF and then if that does not solve the problem clean your IACV. If that does not work, check for an engine code and wiring.

Cleaned... Runs a lot better. The idle still drops around 600 and then jumps back up to like 1000-1100. So better but not done... BUT THEN!!! I look down and im leaking power steering fluid. God damn it. (Glares at 240)
