    As above, I have an ek9 with b18c GSR swapped. Since one week, while driving and mainly on low rpm and re accelerates, I feel a kind of knock and the check engine light turns on. And when on idle, the rpm goes down at times under 1000. What may cause this? Sparks plug? I didn't change them when I did the swap.

    x2 check the cel and see what codes you are getting that will give you an idea what you need to look into. Idle below 1k isn't a bad thing 750-900 is a good range depending on your build.
