Was this problem occurring before you changed the plugs? Also, what type and year engine is it?
It could be several problems from what you described. I've had a bad TPS, clogged fuel filter, and clogged cat all cause problems when trying to accelerate. The TPS and filter caused bucking and lurching and never set a code. The clogged cat caused a drastic loss of power but it was fairly smooth. There are several other possible causes depending on which year and motor you have.
