Started the car today for the 1st time, started fine and idled around 1000, it ran for a few mins, i decided to rev to about 3000, and afterwards engine wouldnt stay running unless i held the throttle, Tried restarting and reving to keep the car going a few times, realized the turbo outlet hose had blown off basically cause it wasnt clamped, fixed the reak/clamp but the car currently idles at about 200rpm, not sure why, i check the vacuum lines and everything, the maf is probably good, suggestions would be appreciated. Possibly fuel related not sure :-/
If you cant tell from my writing life isnt great so if you're gonna be a prick and leave negative rep and a ghey comment just know thats pretty lame, i'm sure everyone tired of noob sr20 install threads but i'm a noob, and this is basically my 1st s13 and sr20 i've ever worked on so questions happen, anyhow i'm looking forward to driving and thank you to those that have been helpful.

Make sure the MAF connection is tight wiggle it see if any chages occur,
But more than likely you need to Adjust your Idle Air Control valve it sits under the Intake manifold look inbetween the 2nd? and 3rd? Runner and you will see a plastic screw turn it in whatever direction until desired RPMS are achieved. Also check your Vacuum line under the throttle body make sure thet are capped off in not in use.
Also some ppl forget but on the Turbo intake pipe there is a 1/2 hole used for the Crank/Head breather "T" make sure its connected

You changed the fuel filter right?
If the AIC valve fixed it then forget this... but you might want to check it anyway. When I had an idling problem I had to adjust my throttle position sensor.

Then it felt sluggish, so I got a fuel filter, then a Walbro 255lph fuel pump.

mostly connected? if there is a leak in vacuum or in the intercooler it will run like shit.

i'm gonna test drive later after i rethread the transmission crossmember bolt housings, figure out why the clutch pedal is either in or out instead of out unless depressed, and find a seat, theres probably no leaks and the fuel filter looks aftermarket and fairly clean/new, not sure about the fuel pump.

Take the fuel filter off and try to blow through it (with your mouth). If it's hard, Get a new one.
