Problem w/Acceleration and Fuel Line?? Please Help!!

[speedracer2001]

Well as you can tell I WONT BE HAVING A GOOD HOLIDAY WEEKEND W/THE STANG...

Question: What could be causing this problem?? My car's acceleration has been getting worse and worse over the past couple of month's but now I just cant take it anymore. When I hit the gas my car pulls off real slow. I have the run the rpm's up to about 5000 in order for the car to move. Eventually it picks up speed once I get into the higher gears. But the lower gears are almost at a crawl.

A friend of the family who is a mechanic said that he thought that the fuel injectors probably just need cleaning but I'm starting to think that its more than that. Could it possibly be the fuel pump dying?? or something else??

Any help w/this problem will be geatly appreciated!! Here's my car's specs below:

92 Mustang Gt 5.0
95k miles
5 speed w/a 6 month old clutch
**I also had a tuneup less than a year ago
