Whats up Honda Swap!? I've been lurking here for a long time as a guest and finally decided to post and ask about a swap I just did. I've searched and searched to no avail, so hopefully I get some answers here. I recently put a OBD2b H22A4 in my 2000 Civic sedan (came stock with an OBD2b D16Y7). It runs strong with the exception of it idle surging from about 1500 - 3500 rpm. The Facts: - 1 CEL code (Code 20 - Electrical Load Detector) - P13 ECU (OBD1) - Civic harness - Converted to internal coil - Fire & fuel to all cylinders, and it's not in limp mode. - Car was automatic, and I did the 3 wire to 2 wire IACV conversion with my 5 speed swap. My questions: 1. When I extended the wiring for my alternator, there were 3 wires on the civic harness and 4 wires on the H22 alternator. I left 1 wire disconnected (Green/White) which I later found out needs to run to the 'ALT D' pin on the ECU. Would this throw the ELD (Code 20) and make the car idle surge? Starting the car with the alternator unplugged makes it run the exact same. 2. The EGR is disconnected, would that make the car idle surge? 3. Unplugging the IACV make the surge change from 1000 - 3500 to 1000 - 1200. Is this a sign that the surge is caused by something else? Any help or insight is appreciated fellas! I previously had a boosted OBD1 D16A in the car, so I'm not a noob when it comes to this stuff. Thanks.
