My Toyota Landcruiser V6 diesel (newly bought in 2008 and with 61 000 km on it) had power problems following a change of the oil and air filters (which in turn were done because of excessive black smoke). When I brought it in to the dealer they looked at the fuel injector system and said they recalibrated the fuel injection and changed the nozzles.
This indeed stopped the car from smoking, but the power problems remain: essentially the car jumps a bit in 3 and 4th gear and feels underpowered in all speeds, and even does funny jumping sometimes when shifting. Now the dealer wants to change the rotor heads at a very expensive cost.
Another mechanic is telling me that probably all is wrong is that the feul filter is clogged, and he is basing this on the fact that there are no problems with starting the car, or with acceleration, or with anything else actually- the only symptom is the jumping in 3/4 gear.
The car is 80% of the time driven in the city (unfortunately) and has only ever been fueled in a proper gas station.
Who is right? Please help- I live in Kenya and there is only one official dealer around and they have a terrible reputation, so I’m not sure where else to go.
