Default B16a Turbo, starts but stumbles and doesnt idle

Ok, i just finished my b16a turbo, turn it over with out touching the pedal, it starts runs a 2k then dies. If i give it one third throttle it will run but the rpms go from 2k to 2.5k over and over. IF i let it die its harder to start again.

Things i know

1.) Spark wires are in the right order.
2.) Cams and crank pully line up with TDC
3.) Im running TE with 450s dsm, i tried to lean it out or richen it up with my vfac and no change. I have gas (45 psi), i got only one CEL for ELD (maybe i need better grounds?)
4.) I cant do the ignition timing because i cant get it to stay running but tis the same wiht the dizzy all the way foward, back and in the middle

Any ideas?

ah a couple things that come to mind for me are;

-what shape are your injectors in? they might need to be cleaned. i had the same kind of problem with my ls/vtec. would start rev up to 2.5/3k then die.
-is your IAVC clogged or plugged?
-TE basemap is messed?

you have probably tried a few of these, just thought i'd see how it was going for you. goodluck

nope the iavc should be on the back of your intake manifold, it has two coolant lines going to it, however i dont know if that would cause you that much trouble.

have you figured anything more out?
