Ok so I have a 2002 4.3l V6 2wd 1500 and a while back my SES light came on and I finally checked it and had quite a few codes in there...
P0134
P0135
P0141
P0154
P0155
P0157 (pending)
So after looking up the codes they are all related to the O2 sensors, so I replaced both upstream and the downstream on bank one. And fired up the truck and the SES light was still on, so I checked the codes again and all of them are still there.....
What am I missing??
