Try mo magpalit ka ng HTW at spark plugs.. tapos linisin mo na din yung Throttle Body, MAF sensor, IACV, etc. kung hindi mo pa nalinis?

A tip's from Sir Tevs (ClubNissanSentra Baguio)

For EFI Cars:

Here is what i would do.

1. Remove Battery from car

2. Remove ECU - use 10mm socket wrench - for Sentra's its located in the bottom middle part just above where the Driver's Gas Pedal is to the right. kapag napasukan nang putik ang ECU - use Distilled water to clean it and final clean with electrical contact cleaner - make sure not to create any static and make sure you are properly grounded when touching the ECU

3. Hose Down entire Engine bay to remove mud and debris - now would be a good time to wash the entire car as well

4. Now is the time to clean and degrease/Detail the engine, then rinse down properly.

5. Disconnect MAF, TPS Pigtail connections - Let these Air Dry under the sun, clean AICV with carb cleaner and let air dry, remove air filter, replace or clean

NOTE: - Remove ENtire MAF Assembly from intake tube - Clean MAF Hotwire Sensor with carb cleaner - spray at a distance enough to clean the wire - not too close so you wont damage the hotwire sensor within the MAF Assembly

6. remove intake tube leading to throttle body
- open Distributor CAP & Rotor and clean/flush with distilled water and let air dry if pinasukan nang putik - if wet- just let it air dry

7. Clean the Intake Manifold with a rag to remove as much Debris/Mud or Dirt - clean the throttle body as well.

8. Drain Oil, remove Oil filter, Drain Transmission Fluid, Drain Gas, bleed entire brake system to take out the old brake fluid, pull sparkplugs, clean and let air dry

9. now is a good time to do underwash.

10. pull out all your interior - panels, seats, carpet, everything that you can take out and Hose down the entire interior.

baka makatulong..
