I was messing around with my air fluel gauge and was hooking it up to a different spot,(my wireing was sloppy) so i hooked it up diffrent and then when i started my car i got a cell. It was the left bank o2 sensor witch is one i just changed about 2 weeks ago. Its also the one the a/f gauge is hooked up to. I disconnect the A/F gauge but still getting a cell.

Could i have shorted out the 02 sensor or something??
