When car is idling and running what can Black smoke indicate?
Truly voluminous clouds and a fast idle too? The manifold vacuum line to the injection pump is open and the engine is getting WOT fueling at all times, only the throttle butterfly is keeping it from redlining. BTDT. You can actually drive it back home with judicious use of the dash shutoff knob to modulate the fuel down some. Prolly not what you mean, though. -- Jim
