i got a b18b1 swapped into my 98 civic hx about a month ago if i let my car sit for about 45 min or longer basically when it fully cools down i have issues starting it again it starts sputters and dies and if i hit the gas on and off itll rev and almost die till it warms up. ive replaced plugs wires cap rotor dizzy is newer. someone told me it could be my fuel pressure regulator but if it sits for a few hrs it starts fine just idles pretty low until warm. can the fuel press reg cause this?
