so I'm planning on either getting a new jb4 or going with a tune. currently, I have a jb4 but I've been having issues with it. EWG wires and also with the o2 sensors whenever I have my jb4 plugged in. cause might be because it is an older jb4. IDK which is why I want to buy a new one. the one I currently have has been a headache and I just want to sell it but I'm also not trying to sell someone something that's broken.
any good ways to figure out if everything is working properly? would a log be the only way to figure that out?
