idle surge and knock. Need another set of eyes on this.

[Silverspyder]

E85 and a E3b16g, been battling knock and a bad idle surge for awhile now. Was getting tons of knock then replaced the knock sensor today..knock decreased dramatically but it's still there.

This is at idle, then a few runs around the block. Thoughts?????

Thanks in advance...pretty new with tuning.

Am I wrong to think my front O2 sensor isn't working as it should?

what kind of gas are you running?

running E85, which should be less susceptible to knock.
