I removed the cat from my 5.9 zj and inserted a bung for the rear o2 sensor in the straight pipe. I obviously threw the check engine light. I built my own MIL eliminator to trick the computer but it never worked. After fighting this for 2 days I put the whole vehicle back to stock. I cleared the computer and its now still throwing the code. any advice. I want it to work with the test pipe.
thanks.
