So my wife has a 07 Edge 2wd with roughly 80k on the clock and it's always had this issue where when you are driving it seems to misfire or maybe lose fuel pressure, not really sure. You can be steady on the throttle at any speed and it just starts sputtering. A lot of times it happens going up an incline but not always. You can floor it and it'll stop the sputter or you can let off the throttle completely for a second or two and it will go back to normal for awhile. She bought the car used and bought an extended warranty with it. This problem eventually triggered a CEL about a year or so ago so we took it to Ford and they changed out a fuel injector (can't remember which one but I'll find out). The problem shortly came back but in a very moderate way and since Ford took 2 weeks to change a friggin injector, we've just been living with it.
Now the problem is back with a vengeance! She said the CEL came on again yesterday but by the time she got home from work and I could get it to AutoZone, the code was gone and their readers can't see any stored codes. So what do I think about this you ask? Well I haven't changed the spark plugs EVER, so I'm going to do that this weekend. (Are the plugs really factory Iridium?) But besides buying all new injectors I would like to see if any you guys have had this issue and if so what was your fix. If you haven't had this issue then maybe my description can help you help me diagnose this problem before something really breaks!
Thanks guys!
