Hi everyone, i have just installed a JDM D15B into my 98 DX. I bought the OBDII to OBDI conversion harness and ECU. I fired the car up for the first time today and it has a rough idle and when you give it throttle it hesitates and wont rev smoothly. Theres a couple things im unsure about. I used my original Y7 injectors and O2 sensor. Theres also a white 2 wire sensor on the back of the intake at the bottom that im unsure as to what its for. any help would be greatly appreciated. thanks

Bump, I have the same issue but not sure what's causing it.

Which D15B is it? There were three "flavors," I believe.

This guy is very knowledgeable regarding this swap (assuming it's "the" D15B - 3-stage VTEC). If the link doesn't help, try contacting him.

Good luck,

Sounds like the injectors. y7 injectors are smaller than vtec injectors..
