1994 Civic - Check Engine "Orange" lamp and Engine revs when idling
Two questions realting to my Honda Civic ESI - 1994 model.
1) When I turn on the ignition key there is a Check Engine lamp displayed in Orange which is remaining On for progressively longer. Car not be started until this light disappears. Eventually after 3-5 seconds light turns off and engine starts normally. Is it spark plug or fuel pump related or something else ?
2) Engine revs when idling. The RPM counter shows increasing revs and then decreasing again even when foot is off the accelerator.
