2004 WRX-Just got the 1507 idle control code on my car. does anyone know where the controller is? I tried unplugging a couple sensors near the intercooler outlet,the one to my left,right on top, looking at the windshield didnt change anything when unplugged. Could it be my luck that I can actually REACH a sensor gone bad in this thing for a change? PS: big thanks for the obd2 scanner greasemonkey,my junk internet decided to work,.... I will own a scanner tomorrow afternoon.

I THINK its fixed....had troubles after the first 2 cleanings...but another night of screwing with it seemed to do the trick. No more 2000 rpm idle,AC doesn't bounce it up and down. It still idles a bit high when cold,but seems to calm down,and will drop to around 600 when warm. If anybody else has this trouble, I found that birchwood casey gun scrubber was by far the best cleaner.It got stuff that 45 mins of rubbing alcohol didnt even touch. I used a little WD40 to lube it back up,and even though it took a couple tries,and some serious aggravation,it was WAY cheaper than the lowest price of $250 for a new IACV !!!!!
