Hi, I am new to this forum, my name is Craig and I am from New South Wales Australia. I own a 2002 Nissan Navara D22 3 litre. The vehicle was going ok until recently, I had to replace the (EGV) (Ithink) valve??. Anyway this was due to black smoke coming from the motor and no power. This worked, but now I have inherited another problem. I have noticed that when I am in fourth gear the motor starts to miss. I do tow a caravan and this is more noticeable under load. But I went out yesterday and I notice it miss even when I am not towing. The vehicle had only 114K on the clock, I regularly service the vehicle and the fuel filter has recently been changed. I am hoping that someone out there can help. I am buffled, and what scares me is taking to a dealer and paying big $$$$$ when there was only a minor technical probelm with the car. Can anyone help and give suggestions. Thanks Craig
