Help! Low Oil Pressure And Car Wants To Stall?

[SIN-032]

I have a rb20 32 that idles lower than usual (between 500-800 when its usually around 1000-1200) and when i come to an intersection or break to pull into driveway, street etc.. it wants to stall.

iv just been flicking it into neutral and using the handbrake to slow me at the last 5m so i can still play with accelerator pedal and keep revs higher to prevent the stall but im gettin sick of doing so lol..

And on a probably different situation, my battery light comes on when im on highway and go back to third to clean cobwebs out.. (only to the speed limit of course) and stays on for a while then goes off or just stays on entire time till i switch car off, but have never had a flat when i go to start it..

and i cannot for the life of me figure it out any suggestions/answers guys?

much appreciated!!

could be a number of things:

- split intake hose

- split FMIC hose

- leaking vac somewhere

- dirty AFM

- dirty or broken IAC/AAC

- car needs a service?
