Help! Low oil psi light flickers at low idle
I was hoping one of you seasoned Evo owners could help me out with a concern I have with my new Evo. I just installed a turboXS hp manual boost controller and now my idle drops to around 600-700 rpms and my low oil light flickers off and on. I only have the mbc installed as of right now. I previously installed a Apexi CAI and it would cause the same problem without the mbc. I also had the hks bov installed without the above two mods and it would cause the same problem. I guess what I'm getting at is this normal with any bolt on that would disrupt or modify the amount of air that the maf would register. I have intalled my stock airbox with no mbc and the idle is normal again with no flickering oil psi light. BTW I did use new vacuum line instead of cutting up the original vacuum line when I installed the mbc. It is slightly larger than the vacuum line that came off the stock setup. I removed the vacuum restrictor that is inline with the bov, could that cause a drop in engine rpm at idle? What should the car be idling at parked?

I will try the idle set screw next. I just installed my MR bov and it's works great thus far. I guess my computer is finally learning the mbc cause the flickering oil psi light has gone away and the low rpm idle has leveled out around 850-900 rpms. I will keep you posted. Thanks for the quick reply.

I'm thinking about putting my Apexi CAI back on and see how that will work now with my MR bov. I removed it b'cause of the stalling problem I had. Just got my Apexi GT catback exhaust system also. It's raining parts today folks......

I made the adjustment today and the flicking oil light went away. Can anyone tell me why this switch is so sensitive? That's funny don't remember that light coming on before the mbc or the CAI.

Turn your key to the "ON" position and tell me what lights are staring at you 
The switch isn't sensitive, it's the fact that your engine was on the verge of stalling (accompanied with a drop in oil pressure) that was causing the light to be triggered.
