Hello, So im having this very frustrating issue with my Z Z32 NA, whenever i turned my headlights on my car starts to idle funny the rpms bounce from 500 to 1000 on neutral ( it feels like a vacuum leak ) :tisk: i have a set of HIDs 6k 55w, at first i thought it was my HID kit what my problem was so i changed back to the stock bulbs and the problem was still happening not as bad as when i had the HIDs,

the problem has no effect on the way that the car drives once i go there is no hesitation or any symptoms on the engine, i thought it may be my battery so i checked it and is good, i went to autozone and checked my electrical system alternator seems to be fine, alternator belt is tight, and i know im missing 2 injectors metal clips ( the ones that hold the plactic injector connector down to the injector) could that be the problem?. I was thinking that the problem is electrical related and i was under the impression that the alternator might be on its way out? i dont know, LMK what you think
thank you

Would think the IAA-unit also compensates for other loads on the engine while at idle, such as the alternator and PS, and in addition to the AC.
