Default misfires or sumthing, help

ok, so when my car is at about 2000 rpm's in third, the car seems to misfire and jerks forward a little and then goes good for a little then does it again, then does it kinda rapidly, but only at 2 grand, and then i found it did it in 4th and 5th gear also, so the other day i went to pass somebody and now it is doing it throughout the power bnd, all the way up to redline, kinda strange, plugs are almost bran new, bout 5000 miles on em, thoguht it was the O2sensor cuz it had been out for about 4 months, that didn't help any, except better gas mileage now, , any ideas on what it might be? thanx guys
