92 Bronco problem.....

[SyKo13 5,000+ posts]

So I been trying to figure out what the hell is wrong with it, when I turn it on, it decelerates, then accelerates all hard, then it goes down and tries to shut off then it accelerates again, sometimes it even revs up all the way and doesn't go down, this has been going on for quite sometime now and it pisses me off that I can't figure it out //content.invisioncic.com/y282845/emoticons/furious.gif.fc81ca146dbff91fede3ed290dbc4f4c.gif , anyone have a clue what it might be?

I'm guessing it's some kind of valve that's fecking up, I already replaced my fuel filter, and my worst fear is that its gonna be teh injectors, so if anyone knows please help :-[

TY

Hehe, it's not the cable...

Something with the IAC, TB, TPS, or the EGR.....

Oh well...Just a guess.Dont know much about the underhood workings of autos.My Dad had an old ford and the cable stuck at about half throttle one time.
