My engine will stall as soon as I turn my headlights on, Anyone know what causes this? I check all the ground and they seems fine. The car is perfectly normal when the headlights are off, even with other accessories on like radio, parking lights, wippers...etc. It only stall when I turn the Headlights on, wtf???

 

do you have any aftermarket pulleys?

 

Your iavc valve may not be working right.This valve adjusts the idle accordingly via the ELD unit.In other words,When your lights are turned on,your car needs a little more amperage to run them,so the idle goes up a little.hope this helps.

 

I believe there is a voltage regulator in your alternator and that may be the problem. I am having the same problem in my CRX, but I haven't fixed it yet.

 

then don't turn on the headlights, hehe
