The throttle body cleaner your talking about I believe your suppose to remove the throttle body, and that spray is to remove the gunk that sometimes causes the throttle body to stick. It should say on the bottle. Im not familiar with the 3m your talking about, we use a similiar product from MIGHTY. It hesitates as soon as a load is put on it, sounds like a vacuum leak. At idle, hood open, do you hear anything sucking air?
