i just swaped a b18a1 into my 92 civic hatch ,, im having trouble w/ it running after it warms up it will run fime but as soon as it hits warm it will want to die it starts to spit and sputter i have no idea whats goin on ... it seem like its gettin gas, if u keep the rpms above 2500 it still runs as soon and u take your foot off the gas it will die but they restarts w/ no problem. any help w/ this would be great ive tryed everything i can think of .. thanx

 

sounds like you may have a bad idle air control unit or mabey a bad throttle position sensor, is the check engine light on? have you had the trouble codes ran? how well does it run off idle? really sounds like a sensor problem to me
