Hi everyone. I recently got 2 cels that poped up. P0037 for low signal 1/2 o2 sensor and P0300 for multiple misfire. The TJ is running fine, no noticeable symptoms. I checked the wiring, everything looks good. Nothing is damage or broken. I order all new NTK sensors. The only recent change was @Wranglerfix pcm about 1000 miles ago. But I don't think thats the problem.
Could the p0300 code be because of the faulty o2 sensor? What else should I look for? Thanks
