I've been skeptical if there is some vacuum leak since the warm idle still goes up and down about ±50～100.
So I covered the air inlet on the air cleaner housing completely but the engine was still running as if nothing happened. Does this mean there is a huge air leak or is it designed to breath the air from somewhere else???? Thanks in advance (IMG:style_emoticons/default/pray.gif) |

1.) Expansion hoses on the plenum to runners
2.) Crack in the plenum 3.) Runner to head spacer/gasket 4.) Throttle body gasket 5.) Any number of defective hoses that connect directly to the plenum |
