Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace Spark Plugs

Remove the engine cover if applicable.
Use a socket set to remove the spark plugs.
Inspect each spark plug for wear; replace if necessary with OEM specifications.
Set the gap on new spark plugs to the manufacturer's specifications before installation.
Reinstall the spark plugs and torque them to the specified value (typically around 13-15 ft-lbs).

3. Adjust Ignition Timing

Use a timing light to check the ignition timing.
If necessary, adjust the timing by loosening the distributor bolts and turning the distributor until the timing is within specifications.
Retighten the bolts securely once adjustments are made.

4. Inspect and Clean Fuel System

Check the fuel filter and replace if it is clogged.
Use a fuel system cleaner according to the manufacturer's instructions to clean injectors.
Ensure that the fuel being used is of the correct octane rating as recommended in the owner's manual.

5. Examine Intake for Vacuum Leaks

Visually inspect all vacuum hoses for cracks or disconnections.
Use a smoke machine or carburetor cleaner to check for leaks while the engine is running.
Replace any damaged hoses or connections found during inspection.
