Maintenance/Repairs

Don’t know how old your post was but I have the sMe issue. Have spent heaps of time uder the car and may (May) have found the problem. I am not a mechanic and am after advice. At the distrubutor I removed both vacuum hoses attached a longer one to check the diaphram (if it has a diaphram) and air flowed freely back and forth between th two ports. Wirh engine running at idle, this action had absolutly no effect on the idle rpm. What is the go. The manual does not detail the function of monifold and ported vacuums operations in the distributor. Engine 2TZ-FE, no EGR, australia.
