Nissan qg15 engine , mashing gas an engine not revving. Car worked fine earlier. What could be the issue?

If you put it in drive, car moving?? Sounding like pedal sensor

yes it will move when put in drive. i unplugged all coil pack one by one and the engine detected the change, same with air flow sensor and exhaust sensors etc. if i press the accelerator peddle it can be pushed straight down and nothing is happening.

have someone mash the pedal for you with the intake duct off and throttle body visible and see if the throttle opening at all with the movement of the pedal. Could be the throttle body or x pedal itself if is e-throttle, a diag scan of the accelerator position sensor and TPS should tell exactly.

Accelerator pedal position sensor, electronic throttle control or throttle relay are most common on the QGs

turned out to be a little $15 rubber stopper by the gas peddle. seems old one dry rot.

What is the correct level to full in the engine when changing oil in a qg15 engine. The blue is where it full to but what is the bent in the dipstick with the red arrow? Is this the level the oil should be?

By H or just below is fine

Qg15 e-throttle, i need a qt of oil everytime I drive, changed the pcv, tappet pan, cvtc solenoid, and now the oil smoke to go with it. Not constant like piston rings smoke I think it's the valve seals. Has anyone ever changed valve seals on a qg? I have a head and block rest down but I'm just asking around.
