Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.
Gather tools: OBD-II scanner, socket set, torque wrench, multimeter, and basic hand tools.

2. Addressing Error Codes

Plug in the OBD-II scanner and retrieve any error codes.
Note down the codes and research their meaning to identify the root cause for the warning light.
Clear the codes and take the vehicle for a test drive to see if the codes return.

3. Inspect and Replace Spark Plugs/Ignition Coils

Remove the engine cover if applicable.
Using a socket wrench, carefully remove the spark plugs.
Inspect the spark plugs for wear; replace with OEM specifications if necessary.
Test ignition coils with a multimeter; replace any that are out of spec.

4. Check Engine Mounts

Visually inspect engine mounts for cracks or separation.
If damaged, remove the old mounts and replace them with new OEM mounts, torquing to manufacturer specifications.

5. Inspect Fuel System

Check fuel pressure using a fuel pressure gauge; replace the fuel filter if pressure is low.
Clean or replace any clogged fuel injectors.

6. Test Drive and Reassemble

Reconnect the battery terminal.
Start the engine and check for any warning lights.
Take the vehicle for a test drive to ensure that the shaking has been resolved and monitor performance.
