Hello fellow Nissan owners,
Recently my Primera P12 2.2 DTI 93kw started having weird issue. Basically when just starting driving car jerks when holding gas steady. It feels like I would be pressing brakes-accelerator-brakes-accelerator that kind of thing while I am just holding gas pedal steady like cruising. Also sometimes you push the gas to the end and the car does not react. Rpm's does not drop but does not go up either. You continue holding it and after around 2 seconds car wakes up and starts accelerating. I have noticed that sometimes while accelerating car instantly loses power while still holding pedal then it continues to operate normally. When driving for around 10-15 km problem is 90-95% gone. Sometimes it loses power like mentioned before but it happens very rarely and for like one second only. Also when stopping and starting to drive on warm engine after these 10-15 km problem does not occur. When driving on cold car jerks like crazy So far what I have noticed: It does not depend on gear It does not depend on speed It depends if it has just started or engine warmed up for 10-15 km It mostly happens on cold engine It feels like it is because of some faulty sensor that "does not talk" well with the computer. I suspect something with the fuel system because loss of power feels like diesel has been cut off for few seconds for example something with fuel pump Also my guess was accelerator position sensor but it is weird that on warm engine problem is almost gone I would be grateful for any thoughts and insights. Maybe some of you had same or similar problem?

Is there any possibility it does it when the indicators are on. I would suspect earth fault first and SVC second.

Thanks for reply.
No not really. I was driving fairly straight road for around 70 km's and I didn't had to use indicators at all

If you have not done the earth fix before it is so simple and cures so many issues we can at least eliminate that. I would also be looking at the two main earth straps from the batter. One goes to the transmission the other to the chassis. You must ensue they have no breaks and a sound connection.

Thank you I will check these. I was out for night drive yesterday and car ran like a charm. It was very strange zero jerking on cold engine cruising/speeding nothing. It seemed like problem vanished completely.. However I still think that it will repeat itself

It appears to be fuel pump mechanical part
