Do you have any check engine lights? If you do it is probably a misfire due spark plugs or wires. If not, get catalytic converter checked. Need to make sure fuel pressure is correct as well.

I'm not a mechanic, but I had the same problem with a couple of Chevrolets I drive. Turned out to be a vaccuum problem, and the oxygen sensor on the exhaust. Or even the cataletic converter could be clogged. Just a few suggestins.
