SR20DET swap done, car isnt holding idle and dies

[driftsilvias13]

ok jus finished my swap yesterday. it starts but i have to hold the gas or else it will die. my first guess is a vaccum leak and when reving it sounds like its poping or misfiring. my friends say that my timing is off..im running really rich by the way with no o2 sensor..there is a lot of smoke!. i cant figure it out since i cant really find any vaccum leaks nor do i have a timing gun..ne suggestions?

suggestions
put in an o2 sensor
get a timing gun
check for vac leaks
and lastly
sell your car

adjust the cas

ok we took the valve cover off and adjusted the timing. it idles very low and i cant really get past 3000rpm. i have a skyline gt-r fuel pump and my friends guess is that im giving way too much fuel its flooding and making the spark misfire. i need to get an o2 sensor to tell it to stop giving so much fuel. sounds like an answer to the problem right? any other suggestions?

if it's stock injectors, fpr and ecu, it shouldn't be getting anymore fuel than stock. so i don't really think that's it. can you rev at all past 3000rpms? if not then it's the MAFS or still the CAS (cam angle sensor) on the side of the block needs adjustment.

have you checked the ECU for fault codes?

Your mafs is prolly dirty, even a spec of dirt will fuck it up, or wiring is bad, check it out

i also cleaned the MAFS yesterday...

cant rev past 3k? bad maf or bad maf wiring

o2 sensor doesnt do shit while your idling, just so you know
