New Expy owner, problems during accelleration

I'm new to the forum and to Expeditions however I am an avid Mustang enthusiast. Just bought a 2000 EB Expy w/ 135000 miles about a month ago and haven't had any problems until today. To start off it was really hesitant for a few seconds at about 20 mph then it takes right off, the rpm don't fall they just linger for a moment. Shift points are a little too high at times under very easy accelleration. When shifting into 3rd it really falls on its face and then acts fine after another 500 rpm. Problems are only noticeable at part throttle, with my foot heavy on the gas no problems and the shifts are nice and crisp. The weird thing is that these problems are intermittent seem to be worse if it sits at idle for any period of time and then I take off. Doesn't always do it at the 1-2 shift but definitely at the 2-3 shift. Heard a very slight beep from the dash at one point. Any help would be greatly appreciated.

Re: New Expy owner, problems during accelleration

Sounds like the previous owner had a lead foot. The shift patterns adjust to your driving style. To reset the learning, just disconnect your battery for 15 minutes or so, or you can remove the fuse for the computer (PCM - Powertrain control module). On my 2001, it is fuse #2 - 5A. Leave it unplugged for a while to ensure a reset - 15 minutes or so.

After you put it back together, all learning patterns will be lost. This includes idle fuel trim and shift patterns. See your owners manual if you have it - the procedure should be listed under battery maintenance. To retrain the idle fuel trim: (from my 2001 owner's guide)
1.Complete stop, set parking brake
2. Truck in park, all accessories off, start engine
3. Allow engine to run until reaches normal operating temperature
4. Allow to idle in park for at least 1 minute
5.Turn A/C on, allow it to idle for at least 1 minute
6. Whith foot on the brake pedal and with A/C on, put the truck in Drive (D) and allow it to idle for at least 1 minute.
7. Drive the truck as YOU normally would for several complete shift patterns, to allow it to relearn the shift patterns.

It should be better after that.

Re: New Expy owner, problems during accelleration

You know, I just re-read that, and realize that these problems came all of a sudden after a month... probably not what I said in the last post.

I'm not sure. I had a similar thing happen when the tranny went out on mine, but it also made a lot of noise at the same time. Do you have all gears? Mine lost 2nd all together, and would also fall flat when it hit 3rd. I had a sprag go out in the tranny. The shop told me that ford changed the sprag in 2000 and 2001 to a cheaper one... when they started going out, they began using the original in 2002.

Good Luck.

Re: New Expy owner, problems during accelleration

Thanks for the info, sorry for the slow response I've been away. The problem seems to come and go depending on who is driving the vehicle, I drive it a little faster than my wife. My wife picks up my daughter from school and has to wait for about 45 minutes or so leaving it running so she don't have a heat stroke and the problem occurs as soon as she leaves school and stays for the rest of the day but is gone the next morning. Maybe this info will help diagnose. Thanks
