Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, compression tester.
Safety Warnings: Disconnect the battery before starting work on electrical systems. Ensure the engine is cool before inspecting the exhaust.

2. Inspect and Repair Exhaust System

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Visually inspect the exhaust pipes, mufflers, and catalytic converter for any visible damage or rust.
3. If leaks are found, tighten any loose clamps or bolts. If damage is extensive, replace the affected parts.
4. Use exhaust sealant on any minor leaks.

3. Replace Worn Engine and Transmission Mounts

Sub-steps:
1. Remove any components obstructing access to the mounts (air intake, etc.).
2. Use a socket wrench to remove the bolts securing the old mounts.
3. Position the new mounts in place and torque bolts to manufacturer specifications (refer to the service manual for exact torque values).
4. Reinstall any removed components.

4. Check and Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the engine cover if necessary to access the ignition components.
2. Unscrew the spark plugs using a spark plug socket and inspect for wear or fouling.
3. Replace any worn spark plugs with new ones, ensuring they are gapped correctly.
4. Check ignition coils for damage and replace if necessary.
