So after the work last month, shop mentioned the hoses/sai being in the way was a pain. Sure enough got a leak, codes for air flow, but no CEL as I cleared them. Just makes that cool whiring jet engine sound when starting, then calms after a minute.
Shop said they would look at it for free, hopefully fix hose or connection.
Anyhow, any thing that is bad about just leaving it for a while?
I understand it's just there for extra air during cold starts?
