Thread: Weird Electrical Problem?

So I have been battling a electrical issue for awhile. My car runs fine, a bit lean when cold, but as it warms up it runs fine. Probably just my STI tune. But when I'm driving the car in the morning or night I have to turn my lights on, so as soon as the parking lights come on the a/f's drop, and as my headlights come on they drop farther and the car wants to die when coming to idle. Making it so hard to drive as it wants to foul out. Usually cruising a/f's of 12's. And if I turn my heater on or my defrost, game over of pure 10.0 and impossible to drive because it fouls. I'm pretty confused as it just seems like a draw. But I'm not really sure. Also when the headlights come on, I get mad interference in my radio and it turns to static for awhile, but once driving it starts to kinda come in ok. Any ideas will help greatly!

Could it be the iac valve clogged? My rpms drop when the a/c, lights, and any load on the engine gets turned on but it goes back up

bad grounds?

See I thought grounds, but I'm using all factory plus more. I mean they could be never tested them.

Why would the IACV cause richness when you get a load? Just curious?

Still need some help on this guys! Trying to get my car running good.
