Nissan Pulsar 2013 Problems

If it's a manual it could be that she's trying to drive it in too high a gear and she should change down to a lower one. If it's automatic I would be looking at the engine idle settings to make sure that they are correct and the engine is not idle is not set too low. Changing fuel makes no sense at all.

Some dealers are using extra service items to boost their profitability but I have not had any manufacturer tell me about the need for fuel or air care cleaning. Never authorise work outside the official service and ask for replaced parts to be returned to you.

$14,340 is at the upper end of the used car price range for the model, but it’s still a significant saving over the new car price and in my view it does represent a better deal than buying a new car.

If a car is built in 2013 then it's a 2013 model and that's how it will be judged at resale time. You're probably already getting a big discount because 2014 is nearly over and dealers are desperate to clear any cars from last year.

It's far better to have more ratios, since it keeps the car's engine operating at maximum efficiency for more of the time. Top-end car companies are now going for eight speeders, which are brilliant with diesel engines. But Japanese companies are turning to constantly variable transmissions, which don't have cogs - just adjustable belts that stop at preset ratios - and these are often disruptive and the operating software is poorly tweaked.

The first thing is that it would seem that the so-called fix isn't a fix. Adjusting the idle would seem to be a stab in the dark in the hope it might alleviate the problem. Take it back to the dealer, and refuse to be stonewalled. Demand an answer, and an explanation of what they are going to do about it.
