b18 Rough warm up

As you all know I just put my b18 in and I'm loving it, it's doin great cept when it's cold it starts up rough as hell for the first 30 seconds or so. It atcs like an old carbed engine or something. If I give it gas, it'll clear up after a while, but if i don't give it gas, it wan't to stall...any ideas would be great. After if warms up it runs fine.

no codes?
if not, get an FPR and gauge.
what ecu are you running?

The PR4 ecu, It's not throwing any codes, I'll check again. It started doing it after we cleaned the EACV. We sprayed it with carbcleaner 'cause the idle was all fucked up, fixed the problem, but now I get this. Think that little o ring needs to be replaced?

anyone else have any ideas?

What year manifold is that? are you using the obd0 manifold or the obd1-2?

Good question...I have no idea. Think I could take a couple pics and you could tell? Or is there something I could look for?

if I had a close up pic I could tell.

if there are hard lines (hard vaccuum tubes) stuck all over the manifold and a crap load of vaccuum hoses, then it is obd0.

If its obd0 it will have an FITV which could be the culprit of your problem, but if you have an obd1-2 manifold then im not sure.
