i just dropped a jdm b16 swap in my 91 civic si and did the obd0-obd1 conversion. when i go to start up the car it will take some time before it start but when i start to give it gas it act like it wants to start. some time it do start but when its running it runs rough and when i go to give it gas it cuts off. first i thoght it was a gas problem because i was still using the resistor box, so what i did with that was cut the four red wires and the yellow wire and black tape them togetherand still the same problem. what do u think, on other thing is that if i us starter fuild it will run good, but ones i stop spraying the starter fuild it will idle rough. one reason why i think it my head gasket is because my brand new dealer plugs are very black. i also see the where the head gasket is under the dist i see oil and it looks green is that a sign of a blown head gasket

 

It could be but for the rough idle check the timing cause I Had the same problem with mine! It wouldnt stay runnin an would idle really rough. Just check the timing but for the head gasket it would put out like a bluish color smoke or a pure white smoke. I know that because i just had that porblem

 

well it don,t put out no smoke at all and no check engine light also and for the timimg i think it lined up i don't have lower or upper timing belt cover, what i did to see if it was lined up was i up the to arrows on the pully up and there is to lines on the pully also that line up together, for the bottom all i can tell u is it points up toward the raditor is tha right

Wow, you should practice a little better grammer. Even I almost couldnt read that. It sounds like you have a wiring issue here. we need more info, you have a conversion harness and everything right? have you check injector pulse? I doubt its the head gasket without any smoke.
