I just had the same problem. Sounds like the IAC valve. You should check to see if its pinned correctly in the harness. Mine wasn't and I have to convert from a 3 wire to a 2 wire valve and repin at the ECU. May not be the issue with a prelude but it solved my EK chassis issue.

Same ---- with my obd2b > obd1 P72 conversion.

Look half way down in first diagram. It worked for me. I did the conversion this morning. Of course you need a 2 wire IACV and the plug. I just cut the coolant temp sensor plug off an old harness.
