sentra owners with GA16DNE/GA14DNE HELP!

[kulotz]

goodeve mga sirs meron akong engine na DNE gusto ko pa ibaba yung idling ang problema asan yung idling screw? can someone give me a description? thanks sobrang maapreciate ko yung magreply antagal na nasa akin itong kotse pero hindi ko mahanap yung idling

[Benzmizer]

Hmm, not sure but since both are EFI engines already, I think the settings are pre-set and would need the CONSULT to adjust.

Bring it to a shop that has this special gadget if not an authorized Nissan dealer.

ok sir thanks

nung una tumaas tinanggal ko baterya tapos tumama na yung idling pero parang feel ko mas maganda pa kung nakababa pa ng onte

Hmm, from my experience, idle should be around 750-800. That way, you reduce unnecessary fuel consumed.

You don't need CONSULT to adjust your idle on a GA16 if there's nothing wrong with it.

All you need to do is the following:

1. Warm up and shut off
2. Disconnect fan and TPS
3. Restart and rev 3 times to 3000 rpms
4. Adjust via idle screw, clockwise idle decreases, counterclockwise idle increases
5. Once idle is set, turn off and reconnect TPS and fan

Used to adjust the idling on my car this way. You need to disconnect the TPS, or it'll relearn around the idle adjustment.

Question: what's the idle at, now? If you lower it, you might need to bump up the timing a bit to get it stable. There's instructions on how to adjust the timing on the same page. If you don't have a timing light and can't do it yourself, print out the instructions for whichever mechanic you are going to. Most don't understand the adaptive nature of EFI and will fail to disconnect the TPS during timing adjustment.

[Benzmizer]

There you go, my apologies for the wrong assumption.

* niky: Any chance you could post a pic showing where the idle screw? It seemed our friend here does not know where it is located. Thanks.

sir DE po engine nung nasa page DNE po akin at ibang iba talaga layout hai walang tachometer sentra ko kasi ex saloon pero ramdam ko nasa around 850? kasi dati mas mababa pero tamang tama lang siya . Me timing light po ako at alam gamitin nung mekaniko namin?

pati saan po yung TPS ng mga DNE na makina?? ang daming puwede hugutin na kamukha nung nasa guide? yung mga iba na hinugot ko namamatay engine alin kaya dito?

maapreciate ko ang mga magrereply maraming salamat po

btw eto po itsura nung engine (nakuha ko sa website hindi ito yung makina ko hehe hindi ako makaupload eh pero yan yung saktong itsura ng engine ko)

NP... while it's always safest to go to the dealership for these things, there are some things we can do on our own...


Unfortunately... I've never owned a DNE engine... it looks like the gray plug on the left side is the TPS, but I'm really not sure... it could be the MAF. I'd need a clearer pic with the air tube removed.

[kulotz]

awts hindi ako makaupload pic me clear shot pa naman ako
me nakuha ako from another website

btw sir me wire na pag hinugot ko instant dead agad yung makina tapos yung tunog niya parang nasasakal anung wire kaya yun?

pati sa tingin niyo yung sa bandang wire ng throtle andun kaya idling screw? pag pinihit ko kasi tumataas idling kaso ang problema nakatodo pihit na palayo eh hindi ko parin makuha yung desired na baba.

yun kaya idling screw? kelangan ko lang siguro sundin yung nasa link na binigay niyo para bumaba what do you think sir?

[delphis]

bosing saan nyo po nabili yung timing light nyo?
gusto korin kasing bumili para sa sentra ko.

itong nasa picture mo ay carb type iyong idling adjstment niyan ay nasa gilid ng carburator ang pagkakaalam ko. Sa carb type kasi pag adjust .Hinaan mo muna menor habang inaadjust mo hangin adjust mo iyong pinakamataas . at saka adjust mo na iyong menor. Pag adjust ng menor mas maganda kung mainit na makina mo. Ito lang ang opinion ko.

nasa bahay ko lang eh hindi ko alam kung saan binili ng tatay ko hindi ko rin matanong dahil wala na akong tatay hehe

sir saan po jan ung pangaadjust? i have a webber carburator pero iba ang layout. pati ang efi po ba me pangadjust ng hangin? thanks sir

That's not a carb:


Clearly EFI (check out the fuel injectors by the cylinder head in the pic)

The black box with the gray connector on the left side of the throttle in the pic is the MAF housing. The small round port inside the throttle body is where the MAF wire is. The individual black connectors (four in all) by the cylinder head are for the fuel injectors.

The purplish looking one might be for vacuum... the brown connector above the gray one might just be the TPS, but without seeing it in person, I can't say that I'm 100% sure. This is one of those things where you'll have to consult a mechanic familiar with these engines to find out... or at least try to find the workshop manual.

EFI na po ang Sentra EX (GA14DNE). I used to own one for 9 years until I sold it in 1997.

Re: idling screw, to my recollection, nasa ilalim siya ng of a certain part (can't remember kung TB or the MAF). Its a black thingy and located on the left side when facing the engine. Tinuro lang din sa akin ng Shell mechanic (Pook Ligaya station).

sir saan po jan ung pangaadjust? i have a webber carburator pero iba ang layout. pati ang efi po ba me pangadjust ng hangin? thanks sir

Iyong webber carburator mo saan nakalagay na sasakyan . Iyong GA16DNE na engine Ay may vertical throttle at MAF inside. Kala mo kasi carb type. Kaya efi ang makina mo.

The perks of owning a rare engine... ...sorry... I feel for ya, bro... ganyan din ang feeling ko sa 626 dati.

Consider... at least mas simple siya compared to the regular GA16DE... mas konti ang vacuum hoses and connections, so it's easier to diagnose problems when you're familiar with the engine, already.

And it allows you to put on bigger and better intake tubes...
