Not sure what is causing this issue... Replaced the hosing and intake manifold fitting from the brake booster. Next step I guess is the check valve or the entire brake booster?
What is weird is that I figured if it was vacuum, it would be consistent. The thing is. This issue doesn't occur at all on first start-up when cold. I can drive around for a while without the issue arising. Braking will return the RPM to normal idle of 900-1100 RPMs. Warmed up, though? Braking will dip down to 400~ RPM and almost stall the vehicle out. Super rough feel.
I disconnected the brake lights to see if it was somehow an electrical issue. Not.
Drums with factory brake booster. Anyone have any ideas?
