my 1999 did the same thing and I found out it was my transmission.
accelerator pump inside the carburator
There are several things that can cause your 2003 or Expedition to misfire. The most common cause is a plugged catalytic converter.
Throttle position sensor
Could be a bad throttle body
Without pulling codes, I would quess the Oxygen sensor is weak and needs replacing.
the ignition timing set wronge. BAd accelerator pump in the carburetor
I had the same problem with my 2005 ford expedition... it was my chamshaft....... The repair is expensive... But it fixed the problem......
Putting your foot down too hard on the accelerator.
Its most likely your fuel system, your engine isn't getting all the fuel it needs.. if its not that, then I would bet on electrical system, alternator or battery. Id start out by cleaning out the fuel system since it wont cost you anything (except maybe fuel additives), and putting on a battery charger, and see where you are from there. After that, I would check the alternator at autozone cause they will do it for free. Otherwise its probably going to be your fuel pump not putting out enough fuel.-- Also want to check your air filter to make sure your engine is getting all the proper air from the intake.Answerdon't punch accelerator. sounds like u need new accelerator pump
Yes, because dry ice is so cold that it melts in the punch and lets the hydrogeon gas evaporates from the punch bowl.
it's the air intake taking more air and the belts moving faster
An Electrical Short Cut somewhere would cause it to blow the fuse. A pinch wire would ground the system, and cause a shortcut.
