Question about 1996 Toyota Land Cruiser
My prado idles really rough in drive but is fine in neutral. Appears to be the increased RPM smoothing it out. Does it have a base idle adjustment or is this "preset" with the ECU?? Thanks. Dennis.
Hi djay ,you need to check the vacuum pipes beneath the injector pump it they are intact and test them with a vacuum gauge. The work of this vacuum is such that when you put it drive the vacuum increases the idle speed slightly.

the idle speed control can be adjusted on the pump by turning the adjusting screw that stops the accelerator lever.
