Obvious problem with electronic throttle control system, having a professional grade scanner hooked to the vehicle when the problem happens to view data PID'S for the APP & TPS sensors is the way to find the problem .

Any codes?

Here is the definition. You may need to have someone check the accelerator pedal position sensor and the circuit.

P2138 NISSAN Description The Accelerator Pedal Position (APP) sensor is installed on the upper end of the accelerator pedal assembly. The sensor detects the accelerator position and sends a signal to the Engine Control Module (ECM).
Accelerator pedal position sensor has two sensors. These sensors are a kind of potentiometers which transform the accelerator pedal position into output voltage, and emit the voltage signal to the ECM.
In addition, these sensors detect the opening and closing speed of the accelerator pedal and feed the voltage signals to the ECM. The ECM judges the current opening angle of the accelerator pedal from these signals and controls the throttle control motor based on these signals.
Idle position of the accelerator pedal is determined by the ECM receiving the signal from the accelerator pedal position sensor. The ECM uses this signal for the engine operation
such as fuel cut.

If your check engine light is on have it scanned for fault codes. Also check to make sure you don't have a vacuum leak, you could of pulled a hose loose accidently when you changed your plugs.
Signals from the oxygen sensor, and/or a bad throttle position will also cause engine surge.
Good luck, i hope this helps.

Did you check the bulbs ? If they are Ok,then check you brake light switch which is under your brake pedal. Good luck

They are normally near the top of the brake pedal. Probably held in place with several screws or bolts.

This car uses "drive by wire" technology and uses a sensor to measure gas pedal movement. This sensor the transmits the info to the engine. So there is no mechanical throttle cable. You might have a bad accelator pedal sensor or it could have a loose wire. Take a look under the dash at the pedal and see if you can locate the sensor and verify it is still connected.

IT may be as simple as a failed throttle cable (the cable may have come of its routing too)
Get under the hood and look at the thottle body which you can actuate by hand (van in park, break on) with the engine running the engine should rev by moving the throttle body.
I hope this may have helped,

There is a switch under your break padal, which is responsible for tail lights and gear lock. if that switch is working fine and your tail lights are working fine then check the electronic lock of gear which is under the cover of gear.
