Just had a 2005 Civic come in with a weird idle... turned out to be a cracked vacuum hose behind the intake manifold.

Ever feel like half of car problems are just air escaping where it shouldn't? Those little vacuum leaks can sure make an engine act possessed. Glad you found the gremlin.

Found that same leak on a 2005 Accord last week. It's wild how such a small crack can cause so much trouble.

Tell me about it. My old Civic had a tiny split in a vacuum hose that made it idle like a washing machine full of rocks. Took me forever to track that down.
