Solution
1. Preparation
  • Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, vacuum gauge.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Inspect and Replace Engine and Transmission Mounts
  • Remove any components obstructing access to the engine and transmission mounts.
  • Use a socket set to unbolt the mounts from the engine and chassis.
  • Inspect the mounts for cracks or excessive wear.
  • Replace with new mounts if damaged, ensuring proper alignment during installation.
  • Torque the mount bolts to the manufacturer-specified values.
3. Check and Replace Spark Plugs and Ignition Coils
  • Remove the ignition coils by unbolting them and disconnecting the electrical connectors.
  • Inspect the spark plugs for wear; replace if worn or fouled.
  • Install new spark plugs, tightening to the specified torque.
  • Reinstall the ignition coils and reconnect the electrical connectors.
4. Clean or Replace Fuel Injectors
  • Use a fuel injector cleaner or remove the injectors for cleaning if necessary.
  • If cleaning does not resolve issues, replace faulty injectors with new units.
  • Ensure proper seating and secure connections when reinstalling.
5. Test for Vacuum Leaks
  • Use a vacuum gauge to measure engine vacuum at idle.
  • Inspect all vacuum hoses for cracks or disconnections.
  • Repair or replace any damaged hoses found during inspection.
6. Compression Test
  • Remove spark plugs and insert the compression tester into each cylinder.
  • Crank the engine and record the compression readings for each cylinder.
  • Compare readings to manufacturer specifications; replace or repair any cylinders with low compression.
