Howdy Folks - I have not been impressed with the cold idle quality of my 1985. One of the avenues I decided to explore was changing to a heated 3 wire Oxygen Sensor from the 1 wire unit. After spending about 30 minutes on the job and waiting for the engine to cool overnight, I was shocked at how much more quickly the idle calmed and smoothed out much earlier in the warm up process than ever before. I will add that I had just replaced the Oxygen Sensor with a new single one about 500 miles ago so the results were definitely not a result of just replacing a faulty unit.

Here is the one I bought from Amazon for $21.50 - http://a.co/guTY8FR

Happy Hunting!

Doesn't look like it is a junk one. Maybe bad out the door? Hard to say
