swapped a jdm b16 into a 94 ej1. now i just extented the jdm wiring harness that came with the engine. now heres my problem it idles high like 1500 to 2000 rpms all the time and when it goes below 2000rpms its starts to bog and buck like its going to stall ? now the car came with the map sensor but mine was mounted on the throttle body. can anybody tell me whats wrong?

 

should've just reused your old car harness and just added the necessary wires for vtec and the knock sensor...could've possibly messed up your car by using the jdm harness and extending it...i don't know...gl though

 

any other suggestions

 

you should always use the harness that came for your car when you swap it. it makes life a hell of alot easier.
