The weird thing was that my hid while driving would stay on but my rear brake lights would flash in and out whenever the lights would come on in the dash. The awesome thing is that it got rid of my rough idle too when I was at idle. I thght I was just going to have to live with that thing forever but now it stays at 600 rpms. Hope this helps man.
So what was the fix?
