High or low RPM? Could be worn clutch or, yes, bad plugs. I hate NGK for his issue......

1994 ford ranger extended cab 6 cyl fuel injected 2 wheel drive automatic

This year of ranger had a few flaws, In one case, a break power booster was robbing the vacumm, you can test this by plugging it off and seeing the differance, but you will have limited brakes. This model year had a problem with a vacuum leak on the manifold. You can check these in many ways, but please don't use starting fluid. The rear of the manifold usually on the drivers side where it seals to the block.
Also, in 2 other cases a cracked head has gave me the same problem. It is caused from a loss of vacuum.

Loss of Power at Freeway Speeds

Sounds like itr is not getting enough fuel. Try or check the fuel filter for dirt or water, and also check the fuel pump pressure to see if it meet factory specs.

Improve mpg

Not much. 1. Keep the tires inflated properly; that makes a big diff. 2. Don't carry anything you don't need...keep it light. 3. Use the lowest octane fuel that will work without the engine making noise(knocking or pinging). 4. Never use a roof rack! (Skis or bike, luggage etc) 5. Do your maintenance on time/keep the thing tuned. 6. Don't jackrabbit start. (making the tires go real fast from a stop) Get quickly to the speed you want and stay there. Changing speed uses more fuel. 7. Slow down. After about 55 MPH most vehicles start using relatively much more fuel. 8. Use the air conditioner and keep the windows closed. Newer car air conditioners are very efficient but old cars weren't so some old timers will tell you to not use the air but that's only for older models. 9. Don't leave the engine running when you're not moving. 10. Don't warm-up the engine in the morning to clear the ice. Use a scraper, drive slowly until the engine warms.(but make sure you can see)
