Question car acting wierd??????????????????????????

sup guys i am haveing a problem with my car the thing is that it threw a 171 ses code and the sticky on top lead me to the gear chatter site and it said some thing about long fuel trims and short fuel trims.

i had this happen before and the ses light came on then it went off for like 2 months by it self so im sort of stuck.

Possibly swap injectors from one side to the other to see if the other side goes lean. I wonder is you have a small blockage in one of the injectors. I guess if it wasn't firing then it would make one side run rich as unburnt fuel would be seen by the O2 sensors. There are front and rear O2s before and after the cats. Is it just one O2 showing lean or front and back on one side? one of the 02's could have gone bad? If its bank (a pair of O2's) it could be injetors or plugs.
