Hi everyone! New to this thread and posted in the gen thread already. Hopefully someone can help me out here.

Things you should know -
- 2000 Lexus RX 300
- 178K miles
- Last oil change mid-September

1. Whenever I'm driving and accelerating, my car jerks, like it's having trouble keeping up with the speed I desire.
2. When I'm at a stop light, or stop sign and the car is in Drive but idle, the RPM meter on the tachometer jumps up and down, and the engine/car jerks a little, and when I let off the brake the car kinda rushes ahead before I've even put my foot down on the pedal.
3. Driving on an incline up a bridge, or hill, or accelerating past 60mph the gas pedal feels like it's not even working, while the car jerks frontwards and backwards like it's struggling.

Anyone know what the problem could be?

No idea whatsoever...

Although you'll definitely get better info if you post your issue in the RX instead of the LX section of this forum. The LX is a completely different vehicle.

Could be a throttle body that needs cleaning. If you haven't used a fuel system cleaner that you add to the gas tank, do that first to clean the injectors, valves, etc.
