usually the obdII port shares power with the cig lighter. If there isn't power at the port they can't read the codes since the code reader gets its power from the connector.

see if it is actually the throttle body or something in the pedal or cable. you can manually operate the throttle body while it is cold (by hand, you may have to remove the engine's plastic cover) then go step on the pedal and see if is still sticking. if it still sticks it is in your pedal...
I recommend finding a complete donor truck from your same year model including the harness and computer if you go the 5.4 conversion route. You may also need to swap the transmission to do it right……... The 03 and 04 Expeds still have the 2-valved motor but the block was changed on these to...
Aaaahh, I was having trouble deciphering what vehicle you were talking about having 2 knock sensors. Chevy has had better knock detection for some time now.... Ford has only recently caught up with the new 3V stuff having the 2 knock sensors.
The funny thing is that my stock calibration...
I am confused.... What vehicle has 2 knock sensors? Chevy does and the new 3V Ford motors do but the 2V motors only have one sensor.
Did I miss something?

The newer trucks' ECM actually generates the speedo data. It can only be changed by reflashing the ECM. There is no longer a seperate controller. The trip computer, information center, and gauge cluster all get their info from the ECM itself across the data bus.
If you have a speedometer...
If it has a bad cell it will drop the voltage while trying to start then quickly recover after the load decreases. I would expect it to be able to sit that long in that cold of weather for only a week.... I let mine sit in Chicago for 2 weeks in that weather and it was fine when I tried to...
The wheel size has nothing to do with it. It is the overall circumference of the tire that effects the speedometer.
I am not aware of any way of programming from the dash but I know you can change with most of the aftermarket programmers that add performance too.

well, when it acts up check the voltage at the battery. If the voltage looks good have someone try to crank it. If the voltage doesn't drop when trying to crank then you have an electrical problem with the starter system since it isn't drawing any current from the battery. Is ther an alarm...
If you want to troubleshoot it yourself you can do this.
Remove one battery cable and wire in ampmeter in series (the clamp on ampmeters usually aren't sensitive enough).
See of current draw is excessive if not it must just be a bad battery.
If excessive current draw exists then start...
they have some nice 2 inch lifts available for the 03 and newer that would give a big boost in clearance and the kit is only like 200 dollars or so.

That is a silencer to keep it from making noise at WOT. A good cold air intake for the 3V motor adds some power. I haven't looked at the newer trucks heavily, but the older ones would allow you to remove this piece. You could use a hacksaw and replace the restrictive section with some tubing...
that's weird... if you put in 4x4 and drive it on dry pavement (slowly.....LOL) does it feel like it is fighting itself.
I loved doing 4 wheel drifts in the snow when I lived in Chicago.... The neighbors thouht I was nuts...

they probably had to recall for faulty bumper bearings......
Just kidding, I haven't heard anything. Where is the member APPLEVALLEYFORD when you need him....
