2 March 2004
This is a Quad Throttle Bodies (4 throttles) from Toyota Corolla Levin / Trueno AE101. It is also some times refer to as ITB (Individual Throttle Bodies).
Also applicable to 4 throttles 20v 4AG models since first production from 1991.
This write up attempts to catalogue as many of the vacuum hoses and their routes as possible. Therefore please realize that it is not complete until future notification.
5 feet of thin vacuum line was bought. The retailer effectively gave 5.5 feet. It was just enough for all the changes below. No spare.
The medium and big vacuum hoses have not been acquired, hence not yet changed. It will be catalogue in the future.
