Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Clean Fuel System

Sub-steps:
1. Locate the fuel filter and inspect for clogs; replace if necessary.
2. Check the fuel pump operation by turning the ignition to the "ON" position without starting the engine; listen for a humming noise.
3. If the fuel pump is faulty, remove the fuel pump assembly and replace it with a new one.
Tools Required:
- Fuel line disconnect tool
- Socket set

3. Check and Replace Ignition Components

Sub-steps:
1. Remove the spark plugs and inspect for wear or fouling; replace if necessary.
2. Test ignition coils with a multimeter; replace any that show resistance outside the manufacturer's specifications.
Tools Required:
- Spark plug socket
- Multimeter

4. Inspect and Replace Air Intake Components

Sub-steps:
1. Remove the air intake hose and inspect for cracks or leaks; replace if damaged.
2. Clean the MAF sensor using a specialized MAF cleaner.
Tools Required:
- Screwdriver set
- MAF cleaner spray

5. Test and Replace Sensors

Sub-steps:
1. Disconnect the TPS and use a multimeter to check for proper voltage output; replace if readings are incorrect.
2. Perform a similar test on the MAF sensor and replace if faulty.
Tools Required:
- Multimeter
