Quick question. I have pro 1's in my b16a and my idle seems lopey, however the rpm is at 950 and does not fluctuate when idling. I dont hear the lopiness (if there is such a word) when I stand in front of the engine...however if i go to the back of the car and listen to the muffler I hear the tone fluctuating as a car thats overcammed would sound. What could cause this?

 

They are supposed to sound like that. Enjoy it!

 

Maybe it has a slight miss?

Seems like most modded Hondas have a slight idle miss.

 

Ayut.
