Hello wisconsin xj'ers, im looking for some help with me major electrical problems on my 2000 cherokee.. o2 sensor codes like crazy, jeep barly runs, cant even drive it for the most part. Ive searched this forum and tried just bout everything i could to fix it but no luck and really cant afford a repair shop to spend hours and hours looking at it to figure it out. Me personally im starting to think it could by me ecm with the 02 sensor circuit. So what im asking for is if anyone would be willing to swap out their good working ecm and put in my jeep to see if it runs right then, that way i will finally know if its my ecm or not. Im located in waldo wisconsin, surrounding areas are, fondulac, sheboygan, lomira, random lake, plymouth, cascade, beechwood. please if anyone can help me out that would be great, ive been fighting with this problem for a month now and i need this damn thing fixed! ive searched this site and got great info back and tried pretty much everything people have said but no luck and one guy said go ask this subforum if anyone locally would be willing to do that swap out ecms to see if it runs right that way you will know if mine is bad or not please message me thank you

what codes are comming up for your o2 sensor, lean, rich, non responsive, it could be something as simple as a vaccum leak or a shorted injector dumping too much fuel in to a broken wire somewhere, good luck man

How many miles are on your jeep? Is your check engine light blinking when the jeep is running?
