so i went to a tuner because my car have this code p0300 for a while now and recently the car is running really bad and misfiring a lot. This p0300 code started when we installed the FI LTH and so i went to the tuner because this is what they recommend to me and now the tuner still cant fix the issue and told me i need to get rid/remove the extension bung or J bung that comes with the headers and have the o2 sensor bolted directly to the pipe. Is this going to be a fix to my car or not?
