I took a 45 minute drive down the highway yesterday, and right about when I was getting to where I was going, CEL comes on. Take care of my business and hop to the Advance down the road. It's a P1415. From what I can gather, this happens by way of bad izze-engineering delete kit install, or bad battery voltage. As far as I know, it doesn't have a delete kit, and when I checked the battery with everything off, it was a happy 12.5V. Should I take any precautions before driving it, does anyone have any ideas, and what do I need to look for to determine if it has this delete kit (never heard of it before yesterday)?
