Need some help please...asap

I just got a 2g fuel rail with the stock 2gfpr on it and installed it since i broke my 1g rail with the buschur racing afpr on it , and the BR won't bolt up to 2g fuel rails.

Anyways , my car has been sitting for about 2 weeks. I got everything back together and cranked it up. It was smoking white / foggy looking smoke that didn't really have an odor and felt kind of moist , was this just condensation that has been building up ? It left a little black mark behind the muffler like carbon shot out of it or something.

The car idles at 1900-2100 RPMs and it won't go any lower eeven after screwing the BISS screw all of the way in.

I have a Walbro 255 HP fuel pump , but my FP gauge reads 45psi of fuel pressure at idle (which is 2k rpms atm).

Is my car idling like shit because of the stock regulator being back on ? Was that smoke just condensation from the car sitting ? Feel free to help me out...

First thing, a more descriptive title to the subject at hand will make searching for others much easier in the future.

Did you have any problems prior to the fuel rail swap? Any other work done?

You should be at 43psi without vacuum hose. Assuming you have -20in Hg of vacuum which equals to about -10psi, you should be at 43 - 10 = 33psi with the vacuum hose on. You're basically overrunning the fpr by 12psi which is a lot. I suggest getting another 1g fuel rail so you can use the SX afpr.

Nope car ran fine prior to the fuel rail / fpr swap. I've always had the vac hose on the fpr , on both setups and the gauge was at 43 with the buschur on. I guess I need to get a damn 1g rail >_<
