Toyota 22R Distributor Vacuum Advance query
Posted: Sat Sep 26, 2009 7:00 pm
Hello, can anybody tell me why there are 2 vacuum hoses to the distribitor on a toyota 22r engine, mine is the signal generator type dizzy, it keeps advancing itself too much at low rpm and causing it to ping, there is a hose attatched to both sides of the vacuum diaphram, hoping somebody has studied it and can assist, thank you.
