Hello everyone,
I'm facing issues with my B16 turbo.

Here are some specs:
STD wiseco Pistons 9:5
Eagle rods
Header using ARP
Brian Crower Valve Springs Steel Retainers (BC2010)
Crane camshafts
VMS cam gears
New LMAs
Full MSD ignition kit
Hondata S300 v2

Here's a video of the sounds:


When we have that sound, the lambda goes down to 0.68, and the ignition timing goes around 20.
It's intermittent and ONLY when idling.
When the sound stop the lambda goes back to 1.00 and the ignition to 14/15 degress

Do you have any idea what can be that?

That sounds like a lopey cam there. I hear them msd products are poop. Just going off what i hear. I hope you figure out the problem man.

 

BUMP!!!

NO ideas?
We are checking everything we can in the time we have.
Any ideas would be great!
