Rough Idle Questions?
I got my gryphon today and started running 93 octane in it, before I had the tuner I had a bit of a rough idle. Now I can tell just how much it jumps, anywhere from 570-630. I am wondering what is the average idle rpm? Also I just hit 50k and I don't think the plugs have been changed, what are good plugs to get? Should I get new plug wires? I have researched this all over the googlenet and can't get any specifics. I appreciate the help.
