The turbo-diesel in my 2014 Toyota Land Cruiser Prado used to sit on 1800 rpm to do 100 km/h, now it is over 2100 rpm to do the same speed, and it also is using more fuel. What is happening to my car?
It would seem the engine has lost some of its performance. Have the engine, in particular the fuel system checked. It could be that the fuel-injectors are worn.
