An engine/exhaust manifold question. Her check engine light keeps going on and off, mechanic said it's a cracked manifold. There's a baby rattle sound from under the hood when accelerating. Also, the car takes a long time to accelerate. Exhaust manifold needs to be fixed, but that may stop car from running altogether, because catalytic converter is plugged--setting off oxygen sensor and check engine light.
