hey there i just bought a dx hatchback with b18a swap, didnt really know what i was getting into but i am there. it sputters under acceleration. i have searched all over cant find anything that applys to my situation. it has 4 wires coming from the ecu into the engine compartment. 2 go to the right side into a round plug that goes toward the injectors, plug sit right beside gray box with fins on it. the other 2 go to a round plug at the distributor. it has like a plastic flex pipe intake and the vacuum line that come off the valve cover is not hooked up to the intake. Along with that a metal tube that is connected to that line that is just there no hoses. should i just get a new intake that has the hook up for the line? Does it sound like the 4 wires are goin to the right places? i am getting a 16 fault code and a 1. 02 sensor isnt even hooked up no idea where the wire is for that. the thing sputters and bucks when you get on it but if u back off and ease on it, comes out of the sputtering and runs fine. if anyone can make any sense of this, i tried explaining all symptoms, I just dont know out of all that what would be the biggest part of the problem. please help, thanks
