O2 sensor question.
Please dont shoot me for posting this here but the O2 sensor I have a question about is on a 95 dodge intrepid. The car sets a code when it is cruising at 70 to 75 mph for a long distance (approximately 30 to 50 miles) When I hooked up Auto X-RAY to it showed Bank 1 position 1 being lean. When I go in monitor mode it stays lean. The other side goes back and forth from rich, center, lean. etc. Before I purchased Auto X-Ray I had the problem with it setting a code for O2 sensors. So I replaced both of them. Do you think I have a bad sensor or something else. Im going to switch sides with the sensor and see if the problem follows the sensor. Other then that does anyone have any suggestions? Thanks for your help!!

swap sensors from side to side. If the problem follows the sensor, then you know what to do. If the problem stays on bank1 position 1, then look at faulty injector in that area.

Re: O2 sensor question. (Marcho Polo)
Man, that was a fast response. I hope it is a sensor. The car seems to idle fine. When reading the service manual they dont seem to give a lot of info about what to look for. If there is a short in the wiring or a dirty connector would this cause a lean reading?
