Clean the contacts and condition of all the plugs/sockets on the throttle body and accelerator pedal.

You could do but I should not do too many things at once. if the above fails you could then clean the ecu contacts if you can get to them.

Frank, thank you for your support.
I think I've fixed it. The engine now run well and the problem looks like has been resolved.
