Just to clarify when I said "spray near it" I meant like all around the vacuum hoses. Key to the spray stuff is it says "extremely flammable" on the can. Thats what causes the idle to slightly increase as it sucks it into the intake if theres a leak. But I wouldn't do it with the truck hot. That's asking for trouble since hot headers and combustable aerosols don't play well.
