I drove an older Ranger 4 end speeds were good.

If I remember correctly, each cylinder had 2 spark plugs, total of 8. Not sure how many you have or how many miles is on your truck. Do you have drum brakes on the rear? Check those for proper adjustment. Replace your fuel filter and spark plugs first. Do the octane booster recommendation. Use some fuel injector cleaner at some point. Make sure no vacuum leaks are present, this can drain horse power. These are the cheap fixes you can do.

Maybe the older 4-cyl were slow, but the newer are very peppy. My 2010 will keep up with just about anything out there...while giving me almost 27 mpg's. I've had several 6 cyl. trucks. Yes, good torque and great for towing, but 14 to 15 mpg's is not good for me when regular gas is costing almost $3/gal. Also, I can tow a 2,000 pound trailer without any problems.
