Solution

1. Preparation

Gather tools and parts needed for inspection and repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Fuel System Inspection

Check Fuel Pressure
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to the "On" position without starting the engine to check for proper fuel pressure.
- Compare readings with manufacturer specifications.
Inspect Fuel Filter
- Locate the fuel filter; remove it using a wrench.
- Replace it with a new filter if it appears clogged or dirty.

3. Air Intake System Inspection

Inspect Air Filter
- Remove the air filter from the housing and check for dirt or blockages.
- Replace the air filter if dirty or damaged.
Throttle Body Cleaning
- Remove the throttle body from the intake manifold.
- Clean the throttle plate and bore using throttle body cleaner and a soft cloth.

4. Transmission Fluid Check

Inspect Fluid Level
- Remove the transmission dipstick and wipe it clean.
- Reinsert and remove again to check fluid level; add fluid if low.
Fluid Condition
- Check the fluid for burnt smell or dark color; if present, consider a transmission fluid change.

5. Ignition System Check

Inspect Spark Plugs
- Remove each spark plug and check for wear, fouling, or damage.
- Replace any defective spark plugs with new ones.
Check Ignition Coils
- Test each ignition coil using a multimeter for proper resistance.
- Replace faulty coils as necessary.
