When I'm idling at operating temperature and I pump my brakes my rpms increase slightly, and then returns to normal idle speed. Is this normal?
It takes about 3 hard pumps and then it revs. Everything else is working fine. Not really a problem, but just wondering if this means there is a leak somewhere. Possibly vacuum?
Yes normal. Your brake booster uses vacum, when you pump the brakes you are changing what the motor seems, so the ECU makes up for it.

Makes sense, Thanks for the info.
