Problem with acceleration

Under acceleration, my truck seems like it surges from about 1700-2200 rpm. Does it the worst in 3rd gear. Ive only had the truck for about 3 months. Its an 04' 4.7l 4x4 with 42000 miles on it. Last week I installed a Fastman throttle body. My gas miliage went up about 1 mpg and the surging got alittle better but is still there. I really dont think its the clutch slipping.
Are there any ways test O2 sensors to see if they are bad?
Thanks,
Justin

Ok, I just drove home and from stop light to stop light, accelerating smooth, it didnt surge. Right before I got home I got on it real hard and it surged all the way from 1500 to 2500 rpm.
I changed the plugs 3300 miles ago. Going to replace the TPS this weekend.
