This may not be a bronco but...

I have a 94 Jetta that my wife drives and it has a stutter going down the road. Any speed it will do small jerks as if it was losing fuel but when you are speeding up it doesnt do it untill you start to cruise. I know its a jetta and not a bronco but everyone here seems to know quite a bit on everything I figured I would ask.

How long has it been since the plugs, Cap, & Rotor, and wires have been changed?
This may not be the problem, however as an example, my Chevrolet van was doing the same thing recently. It was missing slighgly under differing loads. It had never had he plugs changed or wires or cap and rotor and it has 75 K on the clock.
After replacing plugs,wires,cap,and rotor I was amazed at how much better it ran. Oh I also changed the air filter too.

good luck

Well as a matter of fact I did change everything. I have a K&N Air filter so just cleaned it. Someone at my work recomended that it could be a fuel pressure regulator. Does that sound right?

fuel pressure reg comes to mind immediately, as does the O2 sensor. My kids Honda would stutter and carry on while under part throttle, new plugs would clean it up for a few miles but the real fix was when he tried to put a mixture gage in one of those pillar pods and smoked the O2 sensor. WHen he replaced it the stutter went away.

I went all out and replaced to whole engine! 450 for a newer 2.0 was a good deal. It also had a new fuel pressure regulator!

I worked on a jetta one time that was doing that and it was the mass air meter. pull codes before you pull the motor....
