So Friday i removed my jb4 as i plan on having my first maintenance check up at the dealership and did not want them to see the tune. I went on vacation and just got home and decided to take her for a spin. Let her warm up and when I got in I noticed the check engine light was on. I drove it down the street and it was jumping like crazy so I put her back in the garage. Any idea why this is happening? I have denso 1 step plugs gapped .22, an intake, and a catch can running on 93 octane. Is the world just telling me to put the jb4 back on and forget the warranty??
