i need an opinion

i am driving a 2002 nissan patrol, na laspag na ng makuha ko,

ang problema eh parang walang power sa una pero pag nakabwelo, matulin na sya, ok na takbo nya,pero pag biglang traffic at napa break,tapos baba ng gear (from 3rd to 2nd) eh bumabagal acceleration at parang nagiipon sya ng power para bumilis na ulit, kelangan eh 1st gear para mabilis acceleration tapos e 2nd gear and so on.. At pagpaakyat at nabitin ka, kelangan eh clutch tapos i rev ng todo at ibitaw dahan ang clutch, para magkapower paakyat, kung hindi mamatay makina nya pag prematurely na release ang clutch or minsan ginagawa ko nagclutch ako while acclerating paakakyat para di mamatay. Minsan naman pagnakabwelo na try try ko pa magdouble clutch para bumilis, at ok naman pero pag mabagal or paggaling sa matulin sa sabay bagal kasi matraffic tapos double clutch eh wala power.


galing na sya sa sikat na calibration center allegedly sabi ng driver namin eh naperahan lang raw kami, sinaksak lang raw sa computer at may pinindotpindot, taas na ng singil sa amin, i'll try to ask again kung ano pinagawa dun sa dating driver ng sasakyan.

kaka pa change oil nya palang at pinalitan na filter, two shop na ang dinalhan nito. both said kelangan gawin dahil may oil leak one shop said something to do with a bearing sa wheel. one shop said kelangan ko pacheck turbo at i pa calibrate.

Check / replace primary & secondary fuel filters and air filter. Baka barado lang ang filters kaya kinakapos ng fuel and/or air ang engine. Kung hindi pa sha mag-improve, pa scan mo sa Nissan or any qualified diesel service workshop.

Sir mukhang sa clutch ang problema nio kung lahat na ng tuneup nagawa nyo na. Looks to me na clutch release bearing na yan. Mukhang naiiwan na nakaclutch pa rin na i istuck up kaya bumabagal ung sasakyan. Hindi na tuloy in sync ang engine at transmission mo. Dahil delayed ang balik or naiistuck somewhere ung clutch mo equals loss of power un.

Pababa mo transmission. Bili ka na ng buong clutch kit(pressure plate, release bearing and clutch disc) para isang bukasan na lang palit na. Do not skimp on the parts, kung release bearing lang ang sira palitan mo na rin ung pressure plate and clutch disc, dahil bukas na ung transmission, sayang ung labor mahal magpabukas nyan mga around 2k ata.

Anyway, may mga 70k+ na ba ung odometer reading mo? Kung mataas na tlga mileage pinapalitan tlga ang clutch. And Pagtumataas na ba rpm lets say mga 4k parang nde bumibilis ung auto? kung ganyan clutch na yan tlga.

Kung todo ang diin mo sa accelarator pedal during accelaration at walang kausok usok sa exhaust pipe, then your problem could be relation to fuel starvation (fuel filter, clogged fuel lines), if meron lots of black smoke, then most likely the fuel system is ok, it could be an late injection timing, or restricted air intake system (look for clogged filter, restricted air hose, turbo)

Hope this can help
