So I took a run with the oem o2 sensor. Its a bit baffling. The car runs better. sounds meaner, feels faster, but the readings are not much different. This is the same thing I noticed when I installed the sensor, The car got quieter, and did not feel to run as hard.
Its actually a little richer sometimes, and after coming to a stop after accelerating, the idle barely dips to 800-900 yet the o2s are the same as before. mid 12s. Before it was dipping to about 600 and running sluggish. It does seem to be a little leaner at cruising, which is fine to me.
So I guess the real question is, how can readings be close to the same, but the car runs better?
Now I am going to move over to other things needed to be done and work out my parts list so I can stat finishing this car. I am hoping to have the AC fixed soon. Its been tripple digits here and its a bit to hot to drive a non AC car.
