Default Stumbles under acceleration

Alright this is what is happening-under acceleration the car stumbles around 2.7k for maybe a second or so then takes off as usual.
This was not happening before I changed throttle bodies fron a stock one to a cnc ported one I picked up used. As the ported one came with all the sensors I just installed it and promptly sold the original. Now I am thinking (hoping) that my problem is caused by a faulty tps.
Could this be the problem? I have another tps from a truck-is it the same part?
Any help is appreciated!

No codes. Spent the morning looking for vacum(sp) hose leaks and didn't find anything. It is also coming down to idle real slow.
