K/R at idle I just got finished with a head a cam install. I'm running open headers. I am very new with hp tuners but I changed my injector rate and then started the car and I was doing a scan and I have some spark knock at idle. Can the open headers cause this? Trick flow 220 heads, tick sns stage 3 cam.
