under very part throttle engine hiccups

[wardie]

I have recently noticed under part throttle upshifting at the lowewr end of rpm I am now experiencing a slight bucking or kinda like small hiccup as I slowly accelerate?

Will only do it once as I am slowly increasing the RPM's.

114,000 miles AC Delco plugs in last year but original spark plug wires. Just started noticing the car doing this more and more anyone have some experience with this?

it could be a lot of things, where do you feel it, in the pedal, in the car, is it a true hesitation in the engine or just a feeling like the mount or clutch is slipping?
