I have a 1999 Chevy Silverado extended cab new body style. The front sensors needed to be replaced. I bought 2 sensors online they were made by Worg Borner. I installed them and cleared the service light. The light came on again. My question is should I buy only a GM sensor? ---

Worg Borner may be a Chinese imitation of Borg Warner, an old but quality car parts brand. Get the trouble code read at a car parts store free to know more. I have never heard that you must buy the original brand O2 sensor. You need to clear the trouble code. I just bought a CAN OBD II code reader for 50 bucks at Harbor Freight that I am itching to use. ---

Sounds lke you might have “shot the messenger” & replaced your perfectly good O-2 sensors. Example if the codes you read were P-0171 “fuel system too lean bank 1” And P-0174 “fuel system too lean bank 2” the most likely problem is a vacuum leak or dirty MAF sensor. Changing the O2’s wont help with those codes. So, what are the codes that you pulled??
