Why would car not want to idle without shutting off and have no power and shake bad

Hello, there are several possible causes for this. The first thing I think of is a lack of air getting to the engine, or a lack of exhaust flow. Basically choking the engine of the ability to perform. Shaking bad can be related to this, or it could be an ignition or fuel system issue. It's a wide-open gas without being able to spend time looking at your vehicle. A vacuum leak could contribute to the concern.
