Solution

1. Preparation

Gather tools and parts for the repair.
Disconnect the battery to ensure safety while working on the vehicle.

2. Check Oil Level and Quality

Remove the dipstick and wipe it clean.
Reinsert and remove the dipstick to check the oil level.
If the oil appears dirty or has debris, proceed to change the oil.

3. Change Engine Oil (if needed)

Tools Needed: Socket set, oil filter wrench, oil catch pan, funnel.
Sub-steps:
1. Raise the vehicle using jack stands and secure it.
2. Remove the oil drain plug and allow the old oil to drain completely.
3. Replace the oil drain plug and tighten to manufacturer's torque specifications.
4. Remove the old oil filter using an oil filter wrench.
5. Apply a thin coat of oil to the rubber gasket of the new filter before installation.
6. Install the new oil filter, tightening it according to specifications.

4. Verify Oil Type and Amount

Ensure the correct oil type (viscosity and specification) is added.
Pour the new oil using a funnel, checking the level with the dipstick after a few quarts are added.
Add oil until the correct level is reached.

5. Inspect Air Intake and Throttle Body

Remove the air intake duct to access the throttle body.
Clean the throttle body with throttle body cleaner if dirt or carbon buildup is present.
Reassemble the intake duct securely.

6. Inspect Fuel System

Use a fuel pressure gauge to check for proper fuel pressure.
If pressure is low, inspect fuel pump and filter for issues.
