The other day I thought that it would be a good idea to clean the intake manifold and throttle body. Took it off sprayed liberal amounts of carb cleaner into the ports and vacuum hose line areas, leaving it spotless from any crud that was there; Bolt it back on and it won't start!? It turns over and starts for a second then shuts off. Moral of the story, Don't fix it if it ain't broke.... Any help would be appreciated.
