I drive a 1988 7.3 V8 Diesel
I was coming home yesterday and I noticed that when I would come to a stoplight the truck would Idle at less then 100 rpm but would not stall out or shut off (which I was afraid it would do). It was cold (around 30 degrees) and I think it may be the O2 sensor. But thats just me assuming. I also heard something about an idle sensor that may cause the problem. Any thoughts?
