Ignition Wires
Anyone have any ideas on what I can use on my Bronco II 2.8L engine for ignition wires??
I have had nothing but problems with the wires since the originals crapped out.
I have had 4 sets of wires on the engine and every set has given me problems.
I have used dielectric grease on each set and that still has not helped. I bought the best wires I could find and still no go?
Any help would be appreciated

What kind of problems are they giving you,a re they misfiring or just plain grounding out before the spark plug? I'm not sure if you've done this already but purchase the stock wires, none of that aftermarket stuff. If that still doesnt help try putting a new coil or distibutor cap and rotor on.

Replaced all the ignition items already, coil twice. No of thise items were the problem. The plug wires just spark to ground. I bought a new set at Tire Warehouse\Double Discount last weekend. I had looked at their wires $13.82 previously and decided not to purchase them. After the problems with the two other manufacturers wires I bought them. I figured what the heck can't be any worse then the expensive set right?
It's like God himself made those wires, what a difference. The vehicle spark arcing is gone.

I am using Autolite #765 plugs. Thats what Ford put in that engine when it was new. The plugs are gapped at .045 which is the suggested plug gap in the manual. The plugs look fantastic, correct color and I neve see any wear on them. I have had this vehicle since 1989. I changed the plugs right after I bought it. There was 42,000 on the engine when I replaced the plugs. I changed then again at 115,000. I swear they could have run another 30,000 but I was changing the rocker arm cover gasgets and had to pull everything apart for that so I changed the plugs out.
If you have any suggestions on a better set, etc. I'm open??

Autolite #765 plugs are the right ones, but the gap is .044, not .045, and believe it or not, just .001 more of a gap can make a big difference in how things operate. I've been using the standard Autolite wires and haven't seen any issues that I know of. Did you put an aftermarket hi-energy coil or ignition (MSD, etc.) on it? If so, you -have- to put the larger hi-energy spiral-wound ignition wires on. I prefer to stay away from Accel products for the most part because of past bad experiences with them, although, quality may have improved since the last time I used any of their products. Speaking of which, I probably need to pull my plugs and take a look at 'em and check the gaps, etc. Also, regardless of what setup you run, you should ALWAYS put the dielectric grease on both ends of your wires. It serves to keep water out and make removal for maintenance easier. Just my $0.02

The little tag in the engine compartment lists the plug gap at .045. I will pull the plugs and change the gap. I do use dielectric grease on all connections, makes pulling those boots a hell of a lot easier with less damage.
The coil is a stock replacement coil. I know a lot of folks run off to grab that Accel item that really isn't required to run the engine.

Your emissions tag should say .044, because I am unaware of any changes between the 2.8 and 2.9, and all the parts I've looked up for either says .044. You -can- gap 'em wider, the only thing you'll have to consider is getting the right wires, etc. and a stronger coil (I prefer the MSD over the Accel, but I would couple it with a 6A, 6AL, or 6 Offroad ignition unit), and whether or not you'll get any detonation inside the cylinders, which is BAD (melted / grenaded pistons and possibly bent rods, worst case).

So hopefully the ignition issues are resolved! I've usually had the best luck with Bosch and Autolite wires and Autolite or Bosch plugs in any Ford I've owned. Some people get the really expensive large diameter high-energy wires, but leave everything else alone, which sometimes kills the wires prematurely. I've also seen the so-called expensive "high quality" wires that were nothing but *****. One of the experiences I've personally had with Accel products was a set of ignition wires on a Ford Pinto (yeah, I know, I know... can't polish a turd... haha) that crapped out in less than a month and the car would not start as a result. We ended up swapping those out with some Standard Motor Products Blue Streak wires (as well as replacing a few other things that the Accel wires fried...) and never had a problem after that, and the guy that bought the car from us never had a problem with 'em last I knew of (this was about 18-20 years ago, and the last time I remember seeing the car was probably 13 or 14 years ago).
