There are hundreds of reasons why this could happen. From bad spark plugs to bad fuel, clogged air filter, clogged catalytic converter etc. I would start off with replacing all the routine maitenance items first like a new air filter, plugs, and fuel filter. Check the fuel pump as well. Then I would check the fuel injection system. It is also possible that your throttle body is dirty. The throttle body has a hose from the air filter housing attached to it,the throttle body is attached to the intake plenum. Loosen the clamp and take the hose off.Do this with a cold engine, DO NOT DO THIS TO A HOT OR RUNNING ENGINE. FOLLOW THE INSTRUCTIONS! Get some carburetor cleaner and spray it inside the venturi and scrub it with a toothbrush. On one side of the throttle body is the connection for the cable, or even a linkage, from the accelerator, turn this in direction of cable to open the throttle plate(inside the throttle body),and continue to clean. It is also possible that you have a problem with the Idle Air Control Valve or your Throttle Position Sensor. Depending on your level of comfort you might either clean that all yourself or have your mechanic run a good diagnostic on it. You did not mention if your vehicle shows some kind of check engine light has. Just my 2 cents and difficult to diagnose without actually being there.....:-) good Luck
