1998 Acura Integra LS B18B1 I just rebuilt my engine and fired it up tonight for the first time. It seems to idle fine and I have good oil pressure 60 psi at 2000 rpm. The problem I am having is that when you open it up there is a lot of delay before the engine revs. What could be causing this? also I am not getting an engine light so I am assuming that no codes are being thrown.
