When installing my cam we lost the one of the coil pack bolts and look everywhere for it but found nothing! Well today I was tweaking around with my wideband and had it idling. I walked inside to get something and when I came out I heard something jingling. I popped the hood looking around for something looks but the sound seemed to be coming from my headers. So I got underneath the truck thinking it was one of the header bolt was loose and the washer was jingling. When I was looking around down there look what I found!
