Nissan Xtrail revolutions go up and down

The safest thing is that the problem is in the centralina or control box, if it were a dirt problem, I would not have to raise and lower the needles of the account.

If the tacometer needles go up alone, it is the problem of the switchboard, but if they go up because the engine is revolutionized, it is possible that the potentiometer has something to do and before touching the switchboard that is more expensive you should take it into account, I have been a mechanic of official service nissan several years and seen any case, and also a year ago I had to change my car
for k accelerated alone.

Hello, you will see the problem that you have in your camon rail in my opinion point is the lane regulator that is housed at the end of this, its work is to keep the pressure on the lane if it is downloaded it costs you to start and if you work badly it has oscillations the engine, if you do not furt it this case you have to focus on the EGR, this model is carried out self -limp site of the EGR, if you take away the battery when you are doing this operation, you are doing this operation. replace this and make a self -learned car but a batteries removed the problem in the EGR that in this model is housed in the motor butterfly.
