5spd or automatic? Tried cleaning the fuel injectors (at least with Chevron Techron gas additive) and throttle body with cleaner? How old are plugs and wires -- OEM?

Still a bit vague... maybe you need a tune-up.

Maybe a plugged exhaust or cat? Do you hear a hissing sound when you are trying to accelerate?

Do a compression test on the cylinders if below 100 time for rings/valves -- if 140+ and all near that then look for a cloughed catylitic converter.
