    I am picking up a 1995 that the current owners says runs rough he has replaced the cap/ wires/ plugs and although it ran a little better still runs rough, I am picking this up Friday and am wondering how is the best way to trouble shoot this, I know when the EEC gets wet this can happen but we both feel that is not the case, please help!

    EGR sticking, TFI module, Vacuum leak. Put a scan tool on it and get the codes. You can always run a whole can of Seafoam through the intake using a vacuum port at the vacuum tree on the top of the upper plenum.

    If I'm not mistaking there are two plug wires that can be crossed and the truck will run however it will run rough, I believe it is 5 and 7. Do a google on that I'm sure you'll find it on there.

    Check firing order first then the timing if still running rough.

    If you have insurance you could just drive it.....many states will let you do that for a few days after you complete the sale as long as you have insurance, that is really what they care about.

    I just followed the link above and took a quick look at all the bulletins on broncos. Most of the stuff wrong with my '95 is covered.
