#12 of 17 I'm Really Confused by countrynewsman

Let me go through the scenario to better expain my original post. I am parked on the boat ramp ready to pull boat/trailer out of water. I shift to 3 (doesn't matter which gear in this case...same thing happens). I have my left foot on brake and right on gas pedal. I ease down on gas and car starts to move, however, stops. I can move gas all the way to floor and engine still just idles and car doesn't move. I turn off engine for a moment...restart...and try the same thing. Car usually will move at this point. Sometimes it doesn't. So...there's some computer problem I'm guessing. Could it be the throttle sensor? The dealer hooked Expedition to their computer and nothing registered as being wrong.

Your tailpipe in the water? Not likely, so maybe this is time to start throwing parts at it. Maybe the dealer will find that is easier than thinking, and the warranty should cover them.

Same thing happened to me today. First time pulling my boat up a ramp in this vehicle. Left foot on brake, right foot to ease up ramp and each time it just sat there and would not accelerate. I ended up taking my foot off the brake and it took right off. I did not have to restart engine.
 
I know the manual suggests using the parking brake until vehicle begins to move. it says this will help to stop will spin.
 
I wonder if this has anything to do with traction control, ABS or Advance-trac as opposed to an actual failure of the vehicle? Seems like it wants to cut power if it thinks you are braking and accelerating at the same time like during an emergency?
 
I'll use parking brake next time and see if I still have an issue.

#15 of 17 "check advance trac" light on by cobalt25

I thought I felt a slight pulsation in the brakes on my '06 Expedition. It's got 65k on the clock and I can't remember if I've replaced the pads yet. Is it possible I haven't?
  
The "check advance trac" light issue could be related to this. Anyway, the pads looked good with maybe three-eighths of an inch of meat showing. However, it looked like there were SLIGHT vertical lines showing on the pads. Would they be wear indicators? No squealing whatsoever.
  
Then , for the bigger issue, the "check advance trac" light came on right after the brake inspection. How can I determine if I really should check the light? Do I have to pay a dealer to run a code or is there a way to do it myself? Any ideas?
  
thanks, Peter

#16 of 17 validity of "check advance trac" light by cobalt25

I removed all 4 wheels on my 2006 Expedition recently to check brake pad wear. When driving operation resumed the "check advancetrac" light came on. I had read somewhere that wheel removal sometimes triggers false reading for the warning lights. Is that true? How do I reset the message? It is getting to be annoying because I can't read the dashboard messages properly with that displayed.
 
thanks, Peter

My traction control light starts to flash for no reason at all on occasion and when I apply the brakes the truck will pulsate and brake pedal goes to the floor. They switched out the module but the truck continues to do the same thing. Anyone else have this issue?
