I have two codes P0301 and P0402.

I have replaced the plugs, wires rotor, cap and the valve behind the breather next to the firewall.

The truck shutters in overdrive. The transmission shop says there is no problem with the transmission.

Hi Nissan-01,

Should be something to do with the EGR system.
