Mausok

[madduck]

Hi, my Sentra B14 is acting up again. Mausok, maitim at amoy gas. Carbon fouled ang spark plugs, lahat. Ang mga nacheck na
1. Tested using ibang distributor, mausok pa din.
2. Bago ang air filter.
3. Bago ang fuel filter.
4. Napalitan ang spark plugs.
5. Adjusted ang idle screw adjust. Walang difference either lean or rich mausok pa din.
6. Okay daw ang fuel pressure.
7. Okay din daw ang fuel injectors, nagbu-burst ng gas, nag stop din. Wala din daw leak ang o-ring sa fuel injectors.
8. Scanned, according sa shop MAF sensor daw at IACV sensor
9. Tested using ibang IACV at MAF, mausok pa din.
10. Tried disconnecting yung front O2 sensor, walang difference.

What else can be causing the unburned fuel? Thanks for you help!

Unless you know a reliable mechanic who knows how to fix Nissans, I'd suggest you bring it to Nissan North EDSA. Para ma-scan (may computer na ito, right?) and they can also bring this back to spec. I still see a lot of Sentra B14s running around so parts and reliability must be pretty good. Kung may computer na kasi ito, at na-change ang battery recently (or before), most likely nabura ang settings.

I myself own a Sentra B17 (Sylphy 1.8V). Also drove a B14 (Manual) before, ganda ng acceleration nito parang sobrang gaan. Lakas lang sa gas pag lagi binibirit.

BTW, I recommended Nissan North EDSA kasi subok ko na sila na matino. I'm not sure about other branches, I'm sure there are good ones too aside from NE.

Thank you sir. I will check it later.

Thank you. That'll be my last resort, bring it to casa. Salamat sir.

Salamat SkyFlakes. Would you know kung nasaan ang temp sensor?
I just want to get this fixed, maybe sell, and move on. :D
