Problems with my Nissan Frontier

Hello partner, I ask you, at the time that the vehicle is in motion, when slightly hitting the gear lever (without taking the change) it reacts? It is only to rule out, how is the period of the changes in the oil filters? Where the air filter is located, it carries a turbulence chamber attached to a duct in the body, well you can disconnect it without the air passing through the filter, there are times that depending on the sector where you live, you can introduce small twigs that hinder the air passage, the same can be done with those of petroleum. bypass or directly pass the pump ducts to the pump without passing through the oil filters and testing if there is a reaction, in a regular basis should be changed every 10,000 km, the EGR valve (recirculation of the exhaust gases) covered due to the carbon generated by the combustion and finally and that in most cases in this engine it is the wear of the oil injection pump Current square that carries the bomb, try to do the basics first, the bomb leave it the last, I hope these tips serve you, greetings

If you go in 4th, the turbo should already be working, which is around 1500 to 2000 rpm, and a whistle is heard when it reacts, check its turbine blades if you can for some wear or strange object that could have damaged them, or if the turbo discharge valve reacts, which is that valve with a thin hose together with the turbocharger ... I hope you help you.

Thank you Roderick1975 I hope you serve the information and check it as you told me
