Oxygen sensor quality.
I am getting a check engine light. A friend who works at the ford dealership read the codes and said it's an oxygen sensor problem... something about a delayed something or other.
This happened within days of having a new exhaust system installed.
Anyhow, I would like to replace both sensors and am exploring my options. I don't want to be a cheapo and have it bite me later but I also like to get the best value for my money... and if I can do some work and save a fair number of dollars even better.
I usually shop at Autozone and Napa.
Autozone gets $58/each for the Bosch 4 wire sensor w/16.5" wire harness.
-or- $54/each for the Bosch 4 wire with a 13" harness.
Ebay has sesnsors advertised for 96 Aerostars ranging starting at about $25 shipped. Although most don't have the connector, I would have to reuse my old connector. And the ones on ebay come in 1, 2, and 4 wire versions.
There are some on ebay with connectors... items numbers 330098065682 and a different one 130036517422 (click to view).
Are the ebay ones crap? And why are there 16.5" and 13" harnesses at autozone, which do I need?
I would appreciate some advice so I can make the right decision.
