Car shutting off

[k20ej8]

My brother has a 97 accord, and around 1000 rpm to 2000 rpm the car will sputter and shut off while driving. I have to give it gas over 2000 rpm to have the car running. It does backfire too from time to time. CEL light is on for 02 sensor but thats always been on for a while now. help!

please let me know if im worng...thats a good chance i have a ford escort doing the same thing now. it has a bad cat because she has a bad o2 for a long time. its at the point now it wont even start anymore.

can you take that honey comb/bee hive thing out the cat so it will be unclogged??

[junior_tm]

i dont think so what you can give it a try is unbolt the car and turn the car on if still doing the same problem it wont be the cat

[k20ej8]

so take the whole catback off and run it? is that safe to run it like that?

won't hurt anything, but it will be loud as all hell.

so take the whole catback off and run it? is that safe to run it like that?no just unbolt the cat from the header u can leave the side to the catback attached. u just need to see if it will rev without the cat blocking it. wont hurt shit.
