That wuld make sense to me. If the computer reads the tps fully off it would send enough fuel to keep the engine at idle. If the RPMs are already higher than what it's supposed to be, then it would give less and less fuel until the RPM comes down to where it should be. Alas if you are idling in nuetral the engine needs fuel.
