Jerks when accelerating

Volkswagen Vento 2006  110000 miles
Hi, everyone. Recently, on a highway, my Vento jerked considerably when starting to accelerate, as if the current was cut. I've replaced the spark plugs with some NKG platinium, that come for this model, but the failure persists. It jerks two or three times and then continues properly and, it you accelerate the car deeply at once, the tugs are not even felt. Might it be that the spark plugs are not appropriate?

Hello, Bezaleel. The spark plugs you mention are good ones, so I recommend you to check the spark plugs wiring as, if they are failed, the car jerks and the engine is not allowed to develop all its power. I also recommend you to tune up your vehicle completely and this means changing spark plugs, checking its wires, cleaning the throttle body, sensors and IAC valve, replacing air and fuel filters as well as the timing belt, synchronizing the distribution system, calibrating the starting time and even checking the fuel pump pressure. With this maintainance, all your problems will be solved.

Hi there. Try getting your inner cv joint checked. If it shaking under hard speed. Thats the cause of it. Youll notice that specially when going uphill and you accelrating. Inner cv joint is the issue. Got mine fixed last year with this issue. Replaced the inner cv joint and was good as gold
