ok i just got done with my b20b p8r head swap and like it will start but the only way to start it is if you give it gas then tryin to start... and if i stop giving it gas it just dies... no mods stock but the one thing it can be is maybe the ecu, its chip but worked on my LS but the timing is maybe off to because i did new timing belt so tell me what you guys think it is.

 

help....
