1997 Buick century with 3.1 lt. v6, when the engine starts it shacks and will not take throttle.
There are 2 electrical plugs on the right side of the coils. A large one and a smaller one. If I pull out the large plug, engine levels out and seems fine. I put plug back and engine ok. If I shut off, and restart engine shakes again.
