I need help!!
I just finished swapping a first gen JDM b16A into my 1991 Civic SI. The car drives great while accelerating..but..if I just cruise with little throttle input it feels as if it's misfiring. There's definitely a hesitation and loss of power and I can hear the motor sputtering. I changed all the plugs, wires, distributer cap and rotor. That seemed to help a bit but the probelm is still there. Another thing to note, the idle is somewhat unstable but I think it's the idle air control valve.
Anyone have any suggestions??

Yes, it sounds as if you timing is off. That would cause the misfire.

yeah, i think the ignition timing got fucked when the engine shipped .happens once in a while

I retarded and advanced the timing over the weekend with no change during test drives. I replaced O2 sensors and still nothing....I'm gonna lose it!!!!!

are your injectors clogged ? usually whn the car loops at idle it's either a vacum leak or the idle just set to high

I didn't remove each injector and check each one, but I did use a high end fuel injector cleaner just after installing the engine. Do you think I should remove each one to check them?
