I am new to this page I have a 2006 King Ranch bought used for 2200$ with 200000 miles had I had clogged cats keep it from going anywhere yesterday I finish up it was a learning experience on how not to just throw parts I spent over 2000$ that did nothing for it but when I learned on how to read fuel trims I was able to figure it I believe everything starts with being able to read fuel trims thanks. I never got a code i was able to use the fuel trim that was 14.6 and the voltage of the 02 sensor bank 2 sensor 2 which was .0640 i learned that it will only throw a code for lean or rich if its 20+ or -20 %
Welcome to FTE. That's a lot of information and some pretty tough questions. If you took your post to the "Performance, Engine and Troubleshooting" forum, you might get some responses. Here, in the intro section, you are not likely to find much help. You may also find some help in the "Newer Light Duty Trucks" forum under the Expedition banner. Last, stop by your state chapter and join them too. There may well be someone close by, who has experienced the same issues.
