Hello, I'm really hoping somebody can kindly help me with this. I googled and was not able to find anything

Recently, about 1 out of 10 times when the car is started, the throttle seems to stick. When the gas pedal is pressed, the RPM's will stay up for 4-5 seconds after the gas pedal is a released. This happens in park, neutral, drive...

It's really dangerous. Literally the car will continue accelerating in drive at full RPM for 5 seconds if you press the gas for half a second...

If I turn off the car and turn it back on again, the issue seems to go away. 50/50 chance

Any ideas
