did you gap your plugs right!!
The most probable reason for the engine to shake at idle is the motor mounts may need replaced. This is generally from the front and rear motor mounts; however, the sides may need replaced as well.
There are several things that can cause your 2005 Chevrolet Malibu to run rough. The fuel injectors may need to be cleaned. The air filter may need to be replaced.
Replace engine cushions
The Vehicle shakes because of the virbration produced by the engine at the stop sing
That's a misfire-ah....
engine rubber mounts or timin out
Had same problem on my 03. Replaced the fuel and air filter and had plugs replaced. Ran like new after. Dont know which its was but a place to start.
Engine miss.
An automobile engine usually shakes when it is being revved due the crank rotation. When revved in neutral, a torque is produced due to the reaction of the motor.
You have a warped rotor. It must be trued at a machine shop or replaced.
My Honda civic 2002 shakes fora few seconds as I turn the engine off.It happened right after replacing the engine mount on the driver's side.
