you know since it's a 4x4 the front and rear axle HAVE to be the same.

Yes something is wrong , most likely nothing serious. Have codes pulled.

did you check connectors fittings under fuse block and socket on ebcm, pls check all ground and power distri bution,

no it does not

It could be that your knock sensor circuit is working perfectly.You may have a knock that it is reading for long periods.
Try running it disconnected, and see if there is a clatter or knock when accelerating lightly.

You could have a vacuum leak.

vacuum switch needs to be replaced.

try selecting from nutreul or less then 3km

If it is only when taking off it could very well be your rear differential. Have gear oil level and gears checked
