What's going on everybody.. I just bought an S13 240sx with an SR20DET swap and I'm having some problems.

The car will occasionally have a rough idle, and will bog down and almost stall after being revved while in neutral. Also, when clutching in from a roll, the RPMs will dip enough to stall out completely.

The car has a Greddy BOV which is vented to atmosphere(previous owner did it), not recirc. Could this cause the problem? I figure that the ECU(totally stock/untuned sr20 ecu) would dump fuel in order to compensate for the extra air that it is expected to take in, while its just being vented out.

Make sense to anybody else? If not, any idea on what it could be? Thinking that I change to a recirculating BOV and hope that fixes everything.
