Hi I'm new to the forum. I have running issues and loss of power in my mk3 vr6 -92. so the problem is that the car jerks while driving and idling. It doesn't rev more than 5000 rpm, It takes always 3s to start even when the car is warm. I have changed the spark plugs and wires, knock sensor( it was broken). I tryed it with the MAF unplugged, but it runs even worse. And when i rev It to 5k rpm and take my foot from the gas It jerk very strong for a while. I tryed the topspeed and it was only 160km/h / 100mph
