So I've been wondering this for awhile why would the previous owner cut my 02 sensor wire. I have a rich misfire which makes my poor EF d16y7 on DPFI (yes its dpfi the guy half assed a swap im currently getting my parts together for a MPFI swap) run like absolute crap on getting out of first gear and sometimes the begining of 2nd gear. So was this a necessary move to not make the engine run lean? Or will I be safe putting the wires back together and being a lot less ashamed of my ride.
Thanks in advance.

Edit: Rewired the o2 sensor and it runs perfect kind of like a different car. None of the hesitation and stuttering. Just wondering if this will have any downsides.
