You didn't say this in the other post. Did you check the Air Flow Sensor? Did the CAI have a fitting for it? I replaced the air box on a Tercel with a CAI and the opening for the sensor was just that much too big, so I sealed it with sensor-safe RTV.
honda's don't have flow sensors, they use two pressure sensors and a differential map.
Ah! Thanks
