My truck needs a new intake manifold gasket, but all of a sudden its been reving up high when in neutral it has a high idling speed, did I touch or move something ?
 
I don't know. Did you? You really gotta give us much more to go on since we're not there with you to see, hear and smell what's going on. We don't even know if you're driving a cub cadet lawn scrubber or a loudstar skulebus painted up to resemble ken keasey's hippymobeel. Why do you believe the intake gasket (two if a v8) need to be replaced?
