So I recently just built a d16 and I’ve had problem after problem from exhaust to fuel delivery to knocking. So finally got the car up and running took it for a couple runs. Now mind you we just got it running the day before and turned on 2-step and bumped the limiter to 8k rpm. Did a pull and after words it was knocking. I have videos to show everything I’m just looking to see if there’s any commons things that break with vitaras that would cause it to knock.
