93 S10 will not Accellerate HELP

My S10 starts fine and idels great. I go to give it gas and it starts to bog down and will even die out. I have replaced the fuel filter and the fuel pump. I have also cleaned the injectors, and replaced the coil. The injectors are spraying plenty of gas. A year ago I replaced the disrtibutor modual. The truck is a 4.3 V with 248,000. Any ideas this one has me blown away.????????????:crying:

Try loosening the converter front flange and give it an inch clearance you may have a plugged converter. If your power is back buy a new converter.

i had a caprice that did that once it turned out to be the hose between the fuel pump and pickup had a split in it
