idle wierd

[OdessaS13]

whenever i turn on my hazards or hold the brake pedal at a stop light the idle drops to 500 the goes back up to 750 and keeps repeating, engine never stalls. 95% of the time its perfectly steady between 700-800. i had the egr code 32 a while ago come on and off almost every other day but for the past month or so it hasnt come up once. i checked the rubber hoses going to the egr and everything seems to be fine, could the egr valve be causing this or is this a grounding problem

car drives perfectly fine and engine is bone stock with hks mushroom intake, can dirty filter attribute to this?

you have automatic? it was normal for me when i had auto for idle to drop at a stop while it was in drive, but if i put it in neutral it'd idle normal, i guess its' cause your car wants to go but your not letting it go blha blah

no, it manual :coolugh: and yeah i figured out 20 minutes ago. its cuz of my headlights wich also happens be the cause of the squeaking sound i complained in my other thread. anyways wenever the popups go up, idle drops and goes back up, drops and goes back up, it annoying and it also causes a weird-ass squeiking sound when i drive.
bad ground and loose housing = problem solved
