Question about 1990 Toyota Corolla
RPM goes up every time i hit the break.
Look for a valve in the hose connected from the brake master's hydrovac going to your engine's intake manifold . check if it is still working, the valve traps the vacuum from your manifold to the hydrovac. Replace valve if air passes it on both sides.
