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??
 
Who knows on that. Read the code and use that to guide you as to what might be wrong.
