Hi Dieseldude,

I just bought a 2nd hand Pajero (Japan/Subic), below are the vehicles specifications:
- 1998 model / 5 doors
- 2.5 TDIC
- 4D56 Engine
- Automatic

The problem:
- mahina sya humatak
- hirap sa pataas na road
- malakas sa krudo (about 4-5 km/liter)

Maintenance performed:
- changed ATF fluid
- cleaned ATF filter (El Dorado does not have the model)
- changed Fuel filter (original)
- changed Air filter (original)

My Pajero is not producing black smoke actually it barely produces smoke, and the automatic transmission is shifting fine, overdrive is also working.

As per the previous owner he had it calibrated more than a year ago and replaced the nozzles 6 months back. What do you think is causing the sluggishness and high fuel consumption?

  1. Blocked fuel supply to the injection pump
  2. Insufficient turbo boost
  3. Incorrect engine to injection pump timing
  4. Injection pump not properly calibrated


Can you give me at least an estimate for the following job scope?
- Recheck injection pump to engine timing.
- Check and or repair turbocharger boost.
- Check and or calibrate injection pump.
- Check and or replace nozzles with original ones.
Sorry, this is not allowed in this forum.

Thank you in advance. You're welcome...
