Occasional Bogging and Bad MPG!

Ok so for the past few months my car has been running like **** and cant quite fig it out. It'll go normal when full throttle and runs fun but sum odd reason on first few take offs when car is started it once to bog out but then it'll run fine on occasion itll keep spuddering the whole time. Also i used to get around 30mpg now my car avg like 22mpg. Any ideas of what it could be? My guess is injectors but not quite sure! Also just had fuel pump and fuel filter replaced.....Thanks

^Wow you didn't even tell him to post it in the problems section.

I would try cleaning the throttle body. But I honestly don't think it's that, it's normally an idle issue with the TB.
