Hi all,
Have a friend's F250 that has 128,00 on the odometer, but new motor last summer. It has an issue at idle. It will stay in open loop, even at 190+ temp. I am planing on scanning it this week, did it last fall, for a diff issue. I was looking around and find conflicting info on this. I remember it was staying open, until you just brought it up from idle, then it goes into closed loop. While at idle it is extremely rich, you cannot stand around it for long, it gasses you out. Was wondering if it is norm for this, could be idle too low, as i said i will put the verus on it this week and watch what happens. The O2 sensor is new Ford sensor done at motor swap, only has the one downstream of the Y pipe connection. Looking for some direction
Thanks in advance, Chris
