Hey guys I have an issue while deceleration I have a slight hiccup or buck. For an example in fourth gear I will be driving at a constant speed at 3k rpms and when I take my foot off the gas and the car is decelerating naturally at a constant rate there will be hiccups or slight bucking w fluctuation of motor pitch similar to a misfire maybe, any ideas guys???

As you have given almost no background information, do an ignition system tune up. Then go from there.
