92 occasional sputtering
I have a 1992 Ranger with 2.3L and stick shift. The last couple of days on the way home it would have an occasional 10-15 second sputtering and slight loss of power at highway speed. Just snaps back to normal afterwards. It happened at cruising speed, so must not be related to acceleration. I am guessing some kind of electrical or ignition problem. Any ideas as to where to start looking?

Scan the computer for trouble codes & post All code Numbers, as they can offer up good trouble shooting clues. Did the problem come about slowly over time, or suddenly after some event????
Check the plug wires to make sure they're securily attached on Both ends, not damaged & routed as the factory had them using all wire looms & stand-offs. Make sure plug gap is in spec.
At idle raise the hood after dark & check for arcs & sparks on all secondary ignition components, maybe spritz each one with a spray bottle of water while watching for a light show, or a change in idle.
Measure fuel pressure & get the vehicle up to date on All due past & present due scheduled maintenance replacement parts, like plugs, wires, O2 sensors, filters, fluids & use OEM, or those that say they meet or exceed Fords specs, so its ready for winter & let us know how it goes.

Fuel quality, fuel pump, fuel filter, EGR, spark plug wires, spark plugs, and ignition components can cause your symptoms. If you also have trouble climbing hills, you can point more towards fuel, or lack thereof. If it is notable after acceleration or deceleration, you may be picking up water in the fuel, which will slosh around and get picked up and delivered to the injectors. If you have a 'light show' on the plug wires with the engine running at idle in the dark, you likely need new wires. EGR can cause 'trailer hitching', as can ignition intermittents.
