Where is bank 2 sensor 1 ?
I put new plugs and boots on my car and
now it idles real high and sometimes shits
off. Is this a loose sensor or does it need to
be replaced? PLEASE HELP......
Usually under the car after the Catalytic converter. If it fails you get a CEL (check engine light). Most are easy to change with a spark plug wrench ... cost about $15 on Ebay. If the CEL comes on then your car will default to a "rich" engine setting resulting in lost power and low gas mileage
