When idling, engine shakes very badly, like a wash machine would with a heavy unbalanced load. If I accelerate, the engine works great. If I put car in neutral, shaking is minimal. If In neutral and giving it gas, no shake or little shake is experienced

How long since a tune-up? Any applicable trouble codes? To check codes yourself, you need an obd2 code reader. Some of the national brand autostores will check codes for free.

The basics for a rough idle is to check for a leak of some kind, fuel--egr--vacuum leak. When the vehicle is in park or neutral, not much load on the engine.
