Hey guys, i need some help with my 2005 legacy non turbo. the engine shakes/misfires only when im at a complete stop, once I take off, the engine seems to settle. I feel like its a vacuum issue bcuz i had a jetta before and it had the exact same symptoms. my mechanic nephew already changed coil with wires and plugs, and a new battery ( not related lol) if anyone can give me any advice or know of common hoses that crack and lose vacuum, that would be greatly appreciated
