Hesitation problem

[kbarrockstar]

My 97 grand cherokee started hesitating upon acceleration about 6 months ago most people told me in was the idle air control, so I replaced it, then I did a throttle body service, then I was losing power so I removed the catylitic converter, still having the same problem, the 02 sensor was behind the catalytic converter and is now gone. Could this have any thing to do with the hesitiation? Any one know any tricks to get this right?

sounds like what my 89 did when I bought it. I changed my fuel pump and fuel filter it fixed my hesitaion problem. You might want to check yours out.
