Could someone explain engine knock? I have an EGR mod on my car and I’m not sure if this is the reason this is happenig. I’m not familiar with engine knocks so this might be nothing at all, however, I’ve read several threads connecting Engine knock to the EGR mod. When I’m at a complete stop the car idles at 500rpm and it slightly sinks down to around 400rpm. then it jumps between 400rpm and 500rpm. The sound the engine makes is noticeable when it hops. Would this be classified as engin knock?

Thanks

No check engine light. I guess it can be like a hiccup. So adjusting the tps a little should resolve? I noticed when the AC is on and idles higher between 500 and 600 the hiccup is completely gone.

When the AC is on, it raises to 500 or so and sounds much better, So I'm going to raise it to the same a Hua has his. I think that would be perfect.

Thanks for the replys!
