A cracked, split or softened hose can let unmetered air into the intake after the MAF sensor, which can show up as a rough idle or a check engine light. Those signs can have other causes, so look for the cause first: with the engine off and cool, go over the hose for cracks, splits and soft spots, and leave running leak tests to a shop.
