What is the basis of you saying the battery should be good?

If it was me, replacing leaky master cylinder will be first priority before idling problem.

For a moment I thought your idle problem was gone.

Window is dark green. It has no corrosion. Has no problem holding a charge or cranking the car over. Dont see any signs to suggest that its going bad. Other than a salesmen trying to sell me something I dont need.

It is gone, it idles perfectly whether braking or having the lights on, ect. The pedal still sinks slowly.

Like the other guy said replace that master cylinder pronto. It's going to get worse to the point that you have no brakes.

So, this Lucas thing is the one fixed the idle problem, I take. That's pretty good.
