Good evening everyone,

I drive a 2010 Toyota Corolla and I’ve been experiencing some issues:

While driving, the car will suddenly rev on its own. This also happens occasionally when the car is idle.

While parked the rpm goes close to 2, thou this rarely occurs.

After driving for about 30 minutes or more, when I stop and shift the gear to Park, the RPM drops below 1, the engine vibrates, and then gradually returns to normal.

While driving especially when climbing a hill the car makes a noise as if it’s struggling to climb. After a few seconds, it becomes stable again.

Things I have done so far:
A. Changed the fuel pump
B. Bought new plugs
C. Serviced the nozzles
D. Changed the injector mouth

When I first changed the fuel pump and plugs, the hill-climbing issue stopped, but after 3–4 days it returned. All the other problems are still present
