The bobbing float can be pushed down or pulled up, no change on warning. Next, bypass it and check wiring.

Another item for anyone that does a coolant refresh. Check the intake for oil residue on runners. At first, I thought it was the DISA valve. The intake seam is starting to separate. All of my brake cleaner inventory kept being used up. Using some high temp RTV, I sealed it. So far, no more oil residue running down the intake runners.

Next time the intake comes off, it will upgraded. Which performance intake fits? Plus upgrade the valve cover to aluminum.
