Wow, I am not the only one here with the Egr valve and the O2 sensor. I had my share of problems, and now that I am almost done paying for it, I am wondering to myself, gee, should I trade it in? I have several problems, but most were under the manufacture warranty, and now that has run out.
One was the car stopped on it's own, couldn't get it started and had to be towed back to the dealer. Wires under the console were burnt out. Don't know how, but they did. Next was, the transmission, I would come to a stop, and then it would bang. Sensor switch for that. Now my check engine light keeps going on. Egr valve! Cleaned it several times and still working OK after a year. Again, check engine light came on, car running fine, O2 sensor!! Ugh, when is it going to stop! Knock on wood, no problems with gas gauge or fuel sending unit...yet. My two Subaru's that I owned, one a Impreza, and the other an Outback both had major problems after the warranty was up. Loved both of those cars, but traded them in because it was too costly to repair and was under the mercy of the dealership mechanics. Heck, maybe I should just stick with American made. Any help with O2 sensor or egr valve on how to replace, please email me! firstname.lastname@example.org Thanks!!!
