warm pressure/ no vac. 2.8
Warm pressure with vac 3.75
My issue is lean running under WOT. The vacuum pressure that creates the higher control pressure does not bleed off. So there is no connection between the upper WUR port (atmospheric air) and the lower port. So once vacuum is applied to the WUR, it remains at the high control pressure and so a lean condition arises.
With the shut off valve I can artificially keep the mix rich. As to blowing air into the WUR top port, similarly I’m trying to figure out why the WUR holds a vacuum indefinitely instead of temporarily.
I’ll post pics of the vacuum lines later, but they are run in the stock manner AND the ports are functioning as they should. Higher vacuuum pressure at idle, lower with throttle.
As to the previous owner. He’s great, and he spoke super highly of you too! I do call on him when I have questions but this LEAN issue was one he said he never sorted out, he had tried but never found an answer and I’m hoping to get to the bottom of it
