no codes. d16z6 motor tranny and ecm swap into my 99 dx.

 

my does this too, same motor as you. turbo running on CROME<-- i think its CROME's fault but i can't pin point it.

anyways it only does it on a cold start, or after sitting in the cold for an hour or two. when it warms up to normal operating temp, it goes away. i'm stumped! i even changed my ECT sensor, so i know thats not it..

sorry not much help, cuz i too, am searching for a solution...
