I just swapped a d15 vtec in my cousins 93 vx hatch, I used the vx wiring harness hooked everything up but some sort of vaccum box that was on the firewall above the intake manifold. i figured that since that the d15 vtec is like the d16z6 and the d16z6 doesnt have that box i left it out. well my problem is the ecu is throwing a code 9 (cyl sensor) and a code 14 ( iacv). The motor would run great and then all of a sudden the motor would die. So if any one has any info it would be greatly appreciated.

Ignore the knock sensor part and the part about moving ECU wires because of the secondary butterflies

Are you using the right ECU? D16Z6/JDM D15B requires a P08 or a P28

the ecu that my cousins had recieved was supposed to be a p08 manual but after installing it and checking the cel codes i found out it was actually an auto, so tommorow we are gonna try to use a p28. ANd thanks for the link I hope that takes care of the code 9 cause the dizzy is only a few months old.
