A yellow warning light has appeared on the dashboard of my car with a wrench. I'm trying to turn it off but to no avail. I've tried disconnecting the battery and pressing the accelerator pedal as shown in YouTube but to no avail. I'm running an OBD scan but no error code appears. I don't have an oil gauge when I open the menu on the turn signal knob.

The RBM gauge panel suddenly increases on its own without using the gas pedal. I have a 1.6 gas engine, and sometimes the car is slow or a 184 error appears with a complete lack of torque.

When on a incline I lose power. And when I press on the gas gas pedal the rpm skyrockets. Any suggestions?
