Sir I was experiencing poor mileage and the car feels underpowered.
However, there are no check engine lights etc. just a ton of black smoke if I accelerate despite servicing each and everything(diesel filter, fuel filter, air filter,etc)
Furthermore, the mechanic is just saying to service the injectors not replace. He says it might cost around 40k and I think it’s too much.
Upon enquiring he tells me there are some components of the injectors that might need replacement. IF NEEDED ONLY THEN
