95 3.2 rough during acceleration and no power

Hi all! New to the site!!! I have a 95 rodeo that runs rough during acceleration and has basically no power at all. Any ideas? I just replaced plugs and wires which helped the rough acceleration but still has no power and is a little rough still while accelerating. PLease help!!!
3.2 4wd. Also, there is a burning rubber smell coming from who knows where! I can smell it when I pop the hood and on the driver side of truck!! PLEASE HELP!!! Getting Desperate!!!

When was the last time you replaced the wires?
