yeah me either but if i had to guess i would say it was tps sensor or a bad o2 sensor. try taking out the ecu fuse for at least 15 seconds, put it back and crank her up that will reset the ecu atleast.

Make sure your car has enough coolant before you go buying parts. If that sensor dosent work/not reading, no vtec.

1. Get engine to operating temp ( wait for fans to come on)
2. Turn ignition off
3. Disconnect the connector from the sensor
4. Measure resistance between 2 terminals on ECT Sensor -
Should be between 200 - 400 Ohms, if not replace the sensor. Also make sure they have a good connection. Its also possible to have missed them while swapping.

The have a tool that measures resistance between electrical connections. You probably know somebody with one.

Like this one:

Did your fans work before the swap?

A s***ty coolant temperature sensor can cause an erradic idle. It will play mind games with the ECU. I would definitely test that first since it is throwing a CEL
