Highway acceleration

I have a 1993 F150 (302) and lately I have been having problems with the acceleration. Just doesn't seem to have the power anymore in towing and in passing on the highway. Normal city driving everything seems fine, just when you need the power to pass, it just doesn't seem to have it. Any help would be greatly appreciated, thanks.

Boy, this could be many things.

-basic tune up
-plugged fuel filter
-weak fuel pump
-plugged air filter
-vacuum leak(s)
-restriced exhaust
-throttle cable streatched out

etc, etc.

Your engine could just be gettin old and tired... my Pontiac has good jam on the highway still, but she's pretty old off the line.

well, check the o2 sensors and do a basic tune up, i bet you will get your power back.
