1999 Mustang 3.8 Litre bucking after installing cats..

hey everybody, im new to the site and looking gor some tips..
i have a 1999 ford mustang 3.8l manual with 125,000 mi that i brought with the two rear cats cut off. i have now install two new cat converter and o2 sensors in the rear at my shop so i can get my car inspected. i know i have to let the pcm relearn but the computer is ready for inspection but sometime the car bucks during shifting or acceleration. im maybe its time to change the fuel filter and sparkplugs. but all in all just wondering whut other people think , any past experiencing???
