It has been my experience that on Ford throttle bodies it's not a problem as long as they are disconnected electrically. (I have done bunches of Fords) Other makes however, I can't say that. I think that Nissans where a little sensitive to things like that though and possibly other makes too.
As far as I am aware, Ford coat the throttle bodies with something "special". I'm not sure if this applies to all of them. Either way, I've been told that they shouldn't be cleaned with the same aggressive solvents that you'd normally use.
Will it not put on the check engine light ? Or will it not need re calibrarion using a code reading computer device when we clean it by removing from the engine.
I have the same edge. It is surging a bit at stop lights. About 300-500rpm difference from normal idle. I was thinking might be throttle body? Was this your issue or just decided to clean it?
