stumble at about 2500

my cars been stumbling around 2500 rpms and then picks back up at like 3000. i also have a code for an 02 sensor and i think thats the problem. i have the two rear 02 sensors because i had them tuned out and didnt reinstall them in the new y pipe. my question is, can i install the rear o2s in the front instead of buying new ones? theyre all the same right?

They ARE interchangable... so go for it. Your O2 sensors are shot!! So seeing the cam you have (did you just change it), my husband and I did the same thing after we installed the MS4. Problem was solved. Hope this helps!!

a retune will not fix the problem.. but i would suggest getting one.. chances are your running rich.

your o2s are shot..

if i were you i would sell the extensions (assuming you have some) and go to autozone and buy vette o2s.. not only do they work better with LTs but you dont have to have the extension either (which many people have problems with)..

they are like 120 or something for a pair IIRC.. been a while..
