I have to change out the bank 1 Sensor upstream on my 04 tahoe. Looked at it under the vehicle but cant for the life of me seem to be able to get at the electrical plug in to remove it. There is no room to get your hand in there and undo it. Any suggestions?? Thru the right font wheel well maybe??
Access to Bank 1 Sensor 1 O2 Electrial connection??
