I would check that the throttle cable moves freely in its sheath. Disconnect it from the throttle spool and with a helper on the pedal see that it moves well back and forth.

I would not use WD40 as a lubricant, it is designed to displace water. With the cable disconnected and elevated I would (over time) add drops of light machine oil or transmission fluid and let gravity work for you in lubing the cable inside the sheath.

If the cable is free I guess it is possible that the throttle body is gummed up so badly it sticks but that seems highly unlikely.... Perhaps the return/tension spring on the throttle body broke?
