need help with this

[my97mitsGSX]

My first problem is my car smokes alot after i've been idling for over 2-3 minutes. Its a white smoke. My temperature gauge reads normal so i'm not overheating and i'm guessing the water pump is still fine? I'm running a full turbo-back exhaust system w/ no cat - APEXi GT DP/Catback. Does anyone know the cause of this?

My second question is, when i'm giving my car 1/4 throttle accelerating, when I hit 4,000 rpms my car starts to buck/jerk a lot and won't let me accelerate anymore. I've only noticed this after installing my APEXi Dual Chamber BOV. When I give it 50% or more throttle it runs fine... I was messing with the adjustments on the BOV and nothing seems to help.

Thanks

I notice you have a a/f gauge, what does it say at the time you are bucking/jerking

its hard to say, it bounces a lot - edit: my apexi auto timer reads in the mid 14's though..which i think is stoich

i'm thinking i'm hitting like fuel cut or something.. it has to do something with the bov b/c that's when it started happening..

Ok, well thats good that it is bouncing around. But you cant really hit fuel cut by installing a Bov, and only driving at 1/4 throttle. So, its not that either. Purhaps the BOV is leaking, and unmetered air is either being sucked in, or metered air is being blown out the new hole. Recheck your mounting, and pressure test the system.
