Negligible benefits to claning the throttle body????? I can tell you it is very beneficial. There are several reeasons why Ford would not suggest it. One is the liability aspect. Some moron sprays half a bottle of TB cleaner in the intake and washes all the oil off cylinder walls then sues Ford. Any major company also has to take care of its dealers and garages. If Ford wanted to they could make vehicles that had virtually no maintenance. BUt why would they? The majority of car owners are not going to home repair things anyway. And then all those high priced income making entended warranties would be garbage. Ford makes great vehicles but it is still a profit oriented company. And that is the bottom line.
