why does my 89 toyota idles high when i turn on my head lights?
check aternator to make shure its out put is correct,engine may be compensating for lack of power to headlamps
brand new alternator, could it be a relay?
How high is "High"? If you mean it increases by 2-300 rpm, that's just the alternator needing that much more speed to compensate for the draw, as told to by the "brain"..if you mean increases by 2000, then I am stumped myself.
