If a car shakes and loses power when idling it can be the spark plug. If a spark plug is fouling, it can cause power losses.
fuel filter could be clogged or the fuel pump is going out on it.
could need a good tune up sounds like it has a miss
There are a few reasons why a car shakes when idling at a red light. Some reasons could be the ignition coil, motor mounts, or spark plug problems.
If your car is shaking while it is idling, it is most likely your automatic choke. The automatic choke is not operating correctly but if you remove the choke and put a lubricant on it, it should stop shaking.
Need more info like what is the vehicle doing when it shakes, is it idling in park, driving down the road, braking, driving at highway speeds, etc.
A power loss can be from a dead or almost-dead battery. If the car loses power on a hill, it might be a fuel injector or fuel pump, if I'm not mistaken.
Try changing the fuel filter.

I sat in my car in the driveway with the car idling, waiting for the kids to come out.
Same as any car with power steering. You can continue to steer the car but with increased effort.
Kinda need more information. Is it just when accelerating, or also when idling in drive? Does it only do it at a certain rpm or speed, or when applying brakes?
what year is your car and engine cylinders
