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.

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.

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

P0325: Knock Sensor Circuit Malfunction

P1101: Mass Airflow Sensor Out of Self-Test Range

P06DD: Engine Oil Pressure Control Circuit Stuck Off

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.
