Low idle in reverse??-Weird

[Rednek]

I've got a problem. When I put it in reverse from park it doesnt like to keep a steady idle. It really likes to go from 200Rpm to 700Rpm back and forth until it dies.

just a idle adjustment???

(I don't know how to adjust these dam EFI engines.)

I don't have no idea why it only does this in reverse, but the idle is not adjustable by you, it is computer controlled based mainly on input from the TPS.

Please read this post http://broncozone.com/forums/index.php?showtopic=14225 .

Good luck,

sorry dude idk what to say...hmm my guess would be either take it to a parts center such as napa or etc...or ford but they will charge the **** outta ya !!! or try buying a computer programmer for it. it will give u more power and let u adjust most anything...

just what i know but im way new to mechanics...lol

Why not start a separate thread and ask for help?

Try to give us as much information about what the problem is, and exactly what steps you have taken to clear the problem up.

It would also be nice if you let us know what mechanical abilites you have, and if you have any tools.

Do you have a reference book like chiltons, or Haynes?

Oh yes.. I searched and found that thread... after you pulled codes you found that you had a bad Throttle Position Sensor (TPS).
