Bad hesitation on a 528e.

Hi all,
I have been getting a bad hesitation while driving, it does not effect idle and the car never stalls. The best way for me to describe the problem is that while driving at either a constant speed or while accelerating all of a sudden it is like I take my foot off the gas. After about 1 or 2 seconds response to acceleration will return and this will go on for the entire time I am driving. Whether it is cold or hot does not seem to matter either. It has been getting worse the last few days and I am hoping that someone can help me pin point the problem. PS The problem seemed to start when I had my Catalytic converter and o2 sensor replaced.
Regards,
Lee Mullican

I would first go back to whomever replaced the cats and the O2 sensors. At the same time they are looking at the work they did have them replace the fuel filter.


Cheers,
Bill

Thanks for responding Bill,
The fuel filter was also changed as I did not mention that in my original post. Can the primary fuel pump (in tank) cause this condition? It seems to happen when turning also.
