(Need Help) 2000 civic si with B18b Ls vtec

[DrAy]

K here it goes, I got an 2000 civic si i put an b18b Ls vtec in to it. But there is one problem, when i go to start it, it wont run with out me giving it gas. i have to keep the gas pedle pushed. it will only run good at 2000rpm any thing lower the car just start dieing.

So if any one know whats wrong can you tell me.

Its a b18b Ls vtec with an Si head.

First you posted in the wrong section, second is it just doing this on a cold start?

And what ECU are you using, I know when I had switched to my Skunk2 ecu to see if a problem I am dealing with was cause of my ecu I had problems on a cold start, I'd have to manually keep the rpm's up by giving it some gas for about 2-3 minutes but then it would be fine
