LT4 My lt4 now has a "stumble"

[TUPELOLT4]

Hey guys! i need some info.
i just put a new exhaust system on my lt4 and did away with my cats and unhooked the rear O2 Sensors but thats it. Now when im driving and i hit the gas prettty hard, the car has a hesitation or a "stumble" and then takes off. Is this the result of the o2 sesor being unplugged?? how can i correct it?
Thanks for any input!!

TUPELOLT4 - I'd say hook the 02 sensors back up or get a tune.

I definitely agree with 6shooter. Those O2 sensors need to be hooked up. And you need a tune to make that baby run right!

AFTER GETTING YOUR TUNE, BE SURE TO SAVE THE !

Have the rear O2s turned off in the ecu if you don't need them. Have the ecu tuned while the guy is in there. Problem solved.
