Hello Everyone,I recently purchased my first car which happens to be the XF. Ever since I got the car, the engine seems to be lacking. The rpm doesn't go above 3 after the 1st or second gear. And when changing the first gears, there sometimes is a jerk while shifting gears. This is my first car and to be completely honest with all of you I really don't know much about cars in general. I really need all of your insight so I can see what I could do. The guy I purchased it from said that the minor service was done 2 months ago, they changed the air filter then. I have no ideas about the spark plugs or the fuel filter. I'm telling you everything I'm facing. The engine really seems to be lacking and the car is 138k km driven. Please help me out, I really don't wanna have to spend a bomb on this car when I just got it.
