Sorry for hating the brand so much. Lol.

Should also be a consideration....

DZMM is really sticking to the case... I guess whoever did the research for them doesn't know how old this "problem" has been going..

Hey, you're an owner... you have a right to bash your own car.

:hysterical:

*glenn, I don't think clogged injectors would do it... unless they clog and suddenly declog. Not impossible, maybe, but piezo injectors would have to degrade really badly, I think, for that to happen. You would notice those issues, like you said... terrible fuel economy... right before things went wide-open ape-**** nuts.

It's possible the tuning is marginal, but as there's still room for tuning, I don't think it's any worse than other comparable direct injection systems.

What I'd really like to see is a diesel expert (Berrima?) from outside Mitsubishi get ahold of one of these cars, just to check.

The manufacturer solution? Cut the floor mats around the gas pedal.

This is another thing I don't get about SUA... in your case, there is a known cause and there are signs before it happens... then afterwards, it still recurs. The same with the inhibitor switch failure (the one that puts the Monty in neutral).

In SUA cases, one time big time. Then that's it.

*Djerms... hmmm... interesting idea... so injectors degrade... start leaking extra fuel... engine goes wild?

Niky.. Possible din kasi, over tweaked na din YuNg engine NG MOntero... Remember it's the same old engine model used in previous Mitsubishi vehicles, they just upgraded the injection pump, turbo and noozles.. Kaya Pag shift mo, imbes na mag idle up Lang NG kunti.. Like yung idle up pag nag turn on Ka NG A.C. , ang nangyayari nag oover idle up sya.. Just like what I did sa auto ko, I tweaked the injection pump to advanced-- Air to fuel mixture yung ginalaw ko..-- kaya imbes na sakto Lang ibigay na diesel, sobra sobra ang binibigay Na diesel NG injection pump sa engine.. Nagloko na.. Kasi nga over tweaked na yung injection pump...

Oo Nga pala.. Nung nag SUA yung auto ko.. May narinig din ako.. Na fuel knock and yung Mga valves ko tumutope... Then boom... Sudden burst of speed... With lots of white and black smoke...

Same Lang ba horsepower and torque NG strada at Ng montero?

Should be bro.... About 175HP+ and 350 N-meter for the VGT variant....

Nag SuA Na din Dati Yung sasakyan ko... Not a Montero... Ginalaw ko Kasi injection pump... Para lumakas pa Ang hatak....

Ganun din ang effect, parang binuhusan ng isang katutak na diesel ang combustion camber.. Buti nalang it happened sa Startoll... Downhill and naka engine brake Ako more than 10secs... Mabuti at wala akong kasabay at that time.. Pero humarurot talaga... Kahit mag preno ako umaarangkada pa din... What I did was just turn off the key na.. Kasi Nung nilagay ko sa nuetral Umabot 5.5rpm.. Then it happened again... Nung Naka idling AKO NG matagal.. Nung pinasok ko sa 1st gear, Bigla nalang nagwild... Then Sobrang usok... Na white and black smoke.. Nuetral and brake then turn off Lang....

Symptoms na Napancin ko before mag sua.. Malakas sa diesel compare sa normal..

Then binalik ko Lang Sa dati yung settings ng injection pump.. Hindi na ulit nangyari....

not sure if this was posted...but here's what the supposed engineer thinks of the recent accident.

Sa trooper 4jg2 din nangyari yan sa amin. Went wild due to faulty injectors. Buti nalang na neutral ng dad ko kaagad. Pero its an old vehicle that lacked maintenance. Injectors badly needed calibration. Problema sa mitsubishi mukhang hit or miss. Yung iba premature failure siguro. All we can do is speculate. IMO, its not driver's error but quality control, but thats just me.
