Thanks, that is reasuring that I'm only having a momentary problem once in a while (actually once or twice a day).
Yeah, my IGN is around 16 when idling, goes up to 37 at times when accelerating. I haven't watched it long enough to really figure out a patern. I'm watching a few parameters to see if I can see a change when I throw a code.
I need to build a few gauges, so maybe this weekend. Now I know who to go to if I have a problem figuring it out.
