Ok. So my friend and I did a B16A swap into a 91 civic SI. Runs fine. We wired up the VTEC associated wires according to a schematic I found which was as follows: A8 - VTEC solenoid B5 - VTEC pressure switch B19- Knock Sensor C8 - 2nd O2 sensor Now, we're getting the following codes: 7, 17, 21 and 22. Is the wiring incorrect? What could possibly be the problem? Thanks in advance. Please!
