I'm having connection issues with the replacement drivers side oxygen sensor. The connector on the wire harness is suspect. I was going to replace the connector with a new pigtail but it seems that I read something in the past about that not being a good idea. Possible high resistance at the splice. After all we are dealing with millivolts here. If that is a bad idea what would you guys recommend? All comments are welcome. Thank you in advance. - Brad

Unless your splice consists of stripped wire twisted together and covered in electrical tape, you will be fine. A proper crimped butt connector will have no problem, and will be good for years to come if proper waterproof sleeve is used.

People write all kinds of bogus :poo: on the internet.
