When at idle shaking and smells like rotten eggs

Rotten egg smell from exhaust is typically caused by sulfur in the catalytic converter burning off. That can be caused by driving the car harder than normal, or harder than previously, making the converter heat up. If you have exhaust leaking into the car, you will smell it.

We will need a better characterization of the "shaking" to help you solve it. Does the shaking stop when you stop, or does it continue? If it stops, it's either in the drivetrain or wheels. If it doesn't stop, engine or trans.

run fault codes as the lack of rotten eggs smell is an indication that the cat converter is not functioning.

rotten egg smell usually means catalytic converter is bad and is probably plugged causing the vehicle to idle rough

if it shakes and smells of rotten eggs, then the catylitic convertor is bad. driveability symtoms are--- lack of power, drop in fuel economy, lack of high speed power, rough idle or stalling are the symtoms of excessive back pressure. due to a plugged up convertor. it should be diagnosed by a mechanic to verify this.

First step is to access the Engine Control Module (ECM) using diagnostic equipment connected to the data link connector of the car, in order to pull out all Diagnostic Trouble Codes (DTC) memored. Even if engine Malfunction Indicator Lamp (MIL) goes off after engine starting, it's possible to find out temporary DTC codes memored in the ECM. Then you will be full informed about bad components (e.g. bad heated oxygen sensor(s), cylinder(s) misfire(s), bad injector(s), bad ignition coil(s), ... etc). Therefore you will be able to repair & replace bad components and reset the ECM.
In the most cases when you smell something like rotten egg there are bad oxygen sensor(s).

Usually the rotten egg smell is a clogged CAT. Is the engine light on and if so did you retrieve any codes?

Your catalytic converter is plugged up,  If you check the exhaust output at the tailpipe you will find it restricted.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/jason_77a19afa8d604dee

just a thought, have your valves checked, make sure theyre adjusted properly, as for the smell, no idea

run the fault codes
indicates a cat converter problem coupled with injector problems

did ya get some bad fuel? take a fuel sample
