15 Toyota rav4 throttle is not oiled. Why?

Air intake system problem, oil supply system problem.

1, 15 Toyota rav4 didn't fill up the throttle because the throttle failed or the intake manifold leaked. After stepping on the accelerator, the speed can't go up.

2, the oil pump can't build enough pressure, the nozzle will not be able to spray enough oil, and the car can't get on the oil after stepping on the accelerator.
