O2 sensor is 21 whats26?

 

Wow all wires on o2 sensor fried or cracked and broke...could this be my loss of power

 

youd be amazed at what an o2 issue will cause as far as how well the vehicle runs. i think there is something in the wiring with mine cause weve already replaced the o2's twice and all the computers, etc seem fine... so best we can figure, there is a loose or corroded wire.
ive discovered a bit of a trick with mine: if i go WOT thru first gear, it will clear it up. the issue is a buck and chug and hesitate thing. it also pops (i guess you could call it a backfire) at the manifold. but like i said, WOT for a few seconds and it wont run rough till it gets started again...
