I have noticed a loss of power when accelerating from a stop. You can press the accelerator to the ground and the car will barely go then approximately 10 seconds later will just take off with full power. The RPMs do not go up when pressing the gas until it starts accelerating. This is not always an issue, sometimes it does this and sometimes it does not.
Do you
have the same problem?

It sounds like the throttle bore is dirty or the throttle pedal position sensor needs to be replaced. We should run the codes first to see if any comes are present.

Here is a generic guide to help you step by step with instructions in the diagrams below to show you how on your car.

Here is how to remove the throttle body in your car and the throttle pedal position sensor in case you need it. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.

I have a P0325, P1101, P06DD codes on the vehicle. Not sure if this helps but I am at a stand still.

The codes you provided are diagnostic trouble codes (DTCs) that are specific to your 2019 Chevrolet Cruze. These codes indicate potential issues with various systems in your vehicle. Here's what each code refers to:

P0325: Knock Sensor Circuit Malfunction

This code indicates that there is a problem with the knock sensor circuit. The knock sensor detects engine knocking or pinging, which can indicate problems with fuel quality, ignition timing, or other engine issues. A malfunctioning knock sensor can affect engine performance and efficiency.

P1101: Mass Airflow Sensor Out of Self-Test Range

This code suggests that the Mass Airflow Sensor (MAF) is reporting values that are out of the expected range during the self-test. The MAF sensor measures the amount of air entering the engine, which is essential for proper fuel injection and combustion. If the MAF sensor is not functioning correctly, it can lead to poor engine performance and fuel economy.

P06DD: Engine Oil Pressure Control Circuit Stuck Off

This code indicates a problem with the engine oil pressure control circuit. The engine's computer (ECU) uses this circuit to control the oil pressure based on various factors. If the circuit is stuck off, it could lead to issues with oil pressure regulation and potentially affect engine performance and lubrication.

So, the codes that jump out at me are the MAF sensor and the oil pressure circuit. Please make sure the engine is full of clean oil with a new filter, also I would swap out the MAF sensor and then clear the codes.

Check out the images (below). Please let us know what happens.
