Nansky,

P50/injector cleaning, san yan sir?

Fuego4x2,

Wala pa kasing nakainstall na voltmeter sa highlander ko how much kaya ang device+labor non? Siguro I'll just visit first my suking battery shop para macheck ko din kung tama yung response ng alternator ko kapag ON lahat ng accessories ng sasakyan.

Gundamwing, Kumusta na ang sasakyan mo? Napaayos mo na? Ano naging solusyon?

Guys, napalinis ko na injectors ng Highlander ko. Maganda ang results:

1. pumino konti ang idling
2. di na gaano mausok
3. better acceleration
4. medyo mas matipid

I paid P280.00 for injector cleaning. Since tinanggal nila ang cylinder cover to
facilitate removal of injectors, nagpa valve tappet adjustment na rin
ako for P150.00 labor charge.

Hindi pa rin na solve ang problem na pag malamig ang engine, mataas ang RPM
pag nasa operating temperature na, bumaba ng konti ang RPM.

Notice ko rin na pag may elctrical load (headlights on, aircon blowers on max level) bumababa ng konti ang idling. Pansin ko rin nay may electrical connection and injection pump - hindi kaya ito ang dahilan. Nabasa ko kasi na ang alternator ay mas mababa ang electrical charge pag mainit ang environment especially after the engine reached its normal operating temperature and tanghaling tapat.

Wild idea: palagyan ko kaya ng relay ang elecrical connection sa injection pump?

Ako ipapa repair ko alternator ko. Di na kasi consistent and charging. Baka may kinalaman ito sa injection pump. Anyway, balitaan mo kami kung papalagyan mo ng relay ang injection pump.

If your pump in non EFI. The only electric is the solenoid cut off switch. I don't think a relay is required because mababa lang ang requirement niya.

Gtootsie,

Bakit pag may malaking electical load may effect sa idling - bumaba ng konti.

Understandable sa gasoline engine pero sa diesel engine nakapagtataka.

Alternator is harder to turn when there is higher demand. This slows the engine a little.

nansky,

san ka nagpalinis ng injectors? parang mura yata ah. I'm interested in having my injectors cleaned too. TIA ;)

Ok, baka nga un ang dahilan. Thanks.

Sa Bacoor, Cavite ako nagpalinis ng injectors. Normally ang mga calibration shops ay may "injector cleaning" service. Labor cost: P200 to 600 for all the injectors - canvass ka lang ng mura.

What they did:

1. Test spray pattern of each injector
2. open up injector to clean internals - springs, nozzle tips etc.
3. brushed and polished injectors with metal polisher
