I just installed a 98 EX motor into my 99 DX body. And i installed the ecu jumper harness and had to swap out the primary O2 sensor with one with correct connector and spliced in the secondary O2 sensor it into the harness. Now its running a little rough when its out of gear and throwing CEL code 41. I already replaced the primary O2 sensor with a denso replacement one and also check the fuse #15 under the dash and its not blown. I need help!
