You should post in the Octavia I section if it's a 1998 car

It does sound like throttle body. You need to remove it and clean it throuroughly

Open the flap and clean the edges, use petrol and a toothbrush maybe, do both sides of the flap. Every bit of carbon needs to be removed.

When escorted, turn on ignition for a while but don't start it, the car then sets the throttle
