Engine running rough on acceleration HELP!!!!

[vtulliano]

Hi guys,
I have a problem. I will try to be as detailed as possible.

One day I washed my car and I took it out for a drive and it started misfiring on acceleration(kind of bogging down) but then went back to normal everytime I pressed the throttle.

I checked all the forums and stuff and did all the required work. I haven't touched the crank position sensor yet.

First I changed fuel filter, spark plugs, sparkplug cables, vacuum lines and then finally the fuel pump. Problem still persists. What else can it be?
I need to check the crank position sensor and I also heard about the oxygen sensor. Somebody has the same problem?

Any help would be appreciated.
