have you had a tune up latley, if not then it could be your distributer cap, roter, spark plugs, or plug wires. If you have had a tune up lately check that your plug wires are in the correct firing order. If that dont stop it then it could be your oxygen sensor, your mapp sensor or your maf sensor, there is also a chance you have a dead cylinder. hope this is helpful. p.s. if its not a tune up issue you should have it hooked up to a computer to diagnose the problem, guessing with sensor problems can get expensive very quikly
